    Gradient-induced long-range optical pulling force based on photonic band gap

    查看更多>>摘要：Optical pulling provides a new degree of freedom in optical manipulation.It is generally believed that long-range optical pulling forces cannot be generated by the gradient of the incident field.Here,we theoretically propose and numerically demonstrate the realization of a long-range optical pulling force stemming from a self-induced gradient field in the manipulated object.In analogy to potential barriers in quantum tunnelling,we use a photonic band gap design in order to obtain the intensity gradients inside a manipulated object placed in a photonic crystal waveguide,thereby achieving a pulling force.Unlike the usual scattering-type optical pulling forces,the proposed gradient-field approach does not require precise elimination of the reflection from the manipulated objects.In particular,the Einstein-Laub formalism is applied to design this unconventional gradient force.The magnitude of the force can be enhanced by a factor of up to 50 at the optical resonance of the manipulated object in the waveguide,making it insensitive to absorption.The developed approach helps to break the limitation of scattering forces to obtain long-range optical pulling for manipulation and sorting of nanoparticles and other nano-objects.The developed principle of using the band gap to obtain a pulling force may also be applied to other types of waves,such as acoustic or water waves,which are important for numerous applications.

    Low-loss and polarization insensitive 32 × 4 optical switch for ROADM applications

    Xiaotian ZhuXiang WangYanlu HuangLiyan Wu...
    875-884页
    查看更多>>摘要：Integrated switches play a crucial role in the development of reconfigurable optical add-drop multiplexers(ROADMs)that have greater flexibility and compactness,ultimately leading to robust single-chip solutions.Despite decades of research on switches with various structures and platforms,achieving a balance between dense integration,low insertion loss(IL),and polarization-dependent loss(PDL)remains a significant challenge.In this paper,we propose and demonstrate a 32 × 4 optical switch using high-index doped silica glass(HDSG)for ROADM applications.This switch is designed to route any of the 32 inputs to the express ports or drop any channels from 32 inputs to the target 4 drop ports or add any of the 4 ports to any of the 32 express channels.The switch comprises 188 Mach-Zehnder Interferometer(MZI)type switch elements,88 optical vias for the 44 optical bridges,and 618 waveguide-waveguide crossings with three-dimensional(3D)structures.At 1550nm,the fiiber-to-fiber loss for each express channel is below 2 dB,and across the C and L bands,below 3 dB.For each input channel to all 4 drop/add channels at 1550 nm,the loss is less than 3.5 dB and less than 5 dB across the C and L bands.The PDLs for all express and input channels to the 4 drop/add channels are below 0.3 dB over the C band,and the crosstalk is under-50 dB for both the C and L bands.

    Incoherent non-Hermitian skin effect in photonic quantum walks

    Stefano Longhi
    885-893页
    查看更多>>摘要：The non-Hermitian skin effect describes the concentration of an extensive number of eigenstates near the boundaries of certain dissipative systems.This phenomenon has raised a huge interest in different areas of physics,including photonics,deeply expanding our understanding of non-Hermitian systems and opening up new avenues in both fundamental and applied aspects of topological phenomena.The skin effect has been associated to a nontrivial point-gap spectral topology and has been experimentally demonstrated in a variety of synthetic matter systems,including photonic lattices.In most of physical models exhibiting the non-Hermitian skin effect full or partial wave coherence is generally assumed.Here we push the concept of skin effect into the fully incoherent regime and show that rather generally(but not universally)the non-Hermitian skin effect persists under dephasing dynamics.The results are illustrated by considering incoherent light dynamics in non-Hermitian photonic quantum walks.

    Advancing insights into in vivo meningeal lymphatic vessels with stereoscopic wide-field photoacoustic microscopy

    894-907页
    查看更多>>摘要：Meningeal lymphatic vessels(mLVs)play a pivotal role in regulating metabolic waste from cerebrospinal fluid(CSF).However,the current limitations in field of view and resolution of existing imaging techniques impede understanding the stereoscopic morphology and dynamic behavior of mLVs in vivo.Here,we utilized dual-contrast functional photoacoustic microscopy to achieve wide-field intravital imaging of the lymphatic system,including mLVs and glymphatic pathways.The stereoscopic photoacoustic microscopy based on opto-acoustic confocal features has a depth imaging capability of 3.75 mm,facilitating differentiation between mLVs on the meninges and glymphatic pathways within the brain parenchyma.Subsequently,using this imaging technique,we were able to visualize the dynamic drainage of mLVs and identify a peak drainage period occurring around 20-40 min after injection,along with determining the flow direction from CSF to lymph nodes.Inspiringly,in the Alzheimer's disease(AD)mouse model,we observed that AD mice exhibit a～70％reduction in drainage volume of mLVs compared to wild-type mice.With the development of AD,there is be continued decline in mLVs drainage volume.This finding clearly demonstrates that the AD mouse model has impaired CSF drainage.Our study opens up a horizon for understanding the brain's drainage mechanism and dissecting mLVs-associated neurological disorders.

    908-920页
    查看更多>>摘要：Optical sensors with in-cell logic and memory capabilities offer new horizons in realizing machine vision beyond von Neumann architectures and have been attempted with two-dimensional materials,memristive oxides,phase-changing materials etc.Noting the unparalleled performance of superconductors with both quantum-limited optical sensitivities and ultra-wide spectrum coverage,here we report a superconducting memlogic long-wave infrared sensor based on the bistability in hysteretic superconductor-normal phase transition.Driven cooperatively by electrical and optical pulses,the device offers deterministic in-sensor switching between resistive and superconducting(hence dissipationless)states with persistence＞105 s.This results in a resilient reconfigurable memlogic system applicable for,e.g.,encrypted communications.Besides,a high infrared sensitivity at 12.2 μm is achieved through its in-situ metamaterial perfect absorber design.Our work opens the avenue to realize all-in-one superconducting memlogic sensors,surpassing biological retina capabilities in both sensitivity and wavelength,and presents a groundbreaking opportunity to integrate visional perception capabilities into superconductor-based intelligent quantum machines.

    Visual observation of photonic Floquet-Bloch oscillations

    Zhen ZhangYuan LiXiankai SunXuewen Shu...
    921-929页
    查看更多>>摘要：Bloch oscillations(BOs),an important transport phenomenon,have been studied extensively in static systems but remain mysterious in Floquet systems.Here,by harnessing notions from photonic analogy,we propose a generalization of the existing BOs in photonic Floquet lattices,namely the"photonic Floquet-Bloch oscillations",which refer to rescaled photonic Bloch oscillations with a period of extended least common multiple of the modulation period and the Bloch oscillation period.Next,we report the first visual observation of such photonic Floquet-Bloch oscillations(FBOs)by employing waveguide fluorescence microscopy.Most significantly,the FBOs surpass the existing BOs in Floquet systems and exhibit exotic properties on their own,including fractal spectrum and fractional Floquet tunneling.This new transport mechanism offers an intriguing method of wave manipulation that may contribute to rapidly developing fields in photonics,condensed matter physics,and quantum physics.

    Multiplexed manipulation of orbital angular momentum and wavelength in metasurfaces based on arbitrary complex-amplitude control

    Guoli HeYaqin ZhengChangda ZhouSiyang Li...
    930-940页
    查看更多>>摘要：Due to its unbounded and orthogonal modes,the orbital angular momentum(OAM)is regarded as a key optical degree of freedom(DoF)for future information processing with ultra-high capacity and speed.Although the manipulation of OAM based on metasurfaces has brought about great achievements in various fields,such manipulation currently remains at single-DoF level,which means the multiplexed manipulation of OAM with other optical DoFs is still lacking,greatly hampering the application of OAM beams and advancement of metasurfaces.In order to overcome this challenge,we propose the idea of multiplexed coherent pixel(MCP)for metasurfaces.This approach enables the manipulation of arbitrary complex-amplitude under incident lights of both plane and OAM waves,on the basis of which we have realized the multiplexed DoF control of OAM and wavelength.As a result,the MCP method expands the types of incident lights which can be simultaneously responded by metasurfaces,enriches the information processing capability of metasurfaces,and creates applications of information encryption and OAM demultiplexer.Our findings not only provide means for the design of high-security and high-capacity metasurfaces,but also raise the control and application level of OAM,offering great potential for multifunctional nanophotonic devices in the future.

    941-956页
    查看更多>>摘要：Photoacoustic spectroscopy(PAS)as a highly sensitive and selective trace gas detection technique has extremely broad application in many fields.However,the laser sources currently used in PAS limit the sensing performance.Compared to diode laser and quantum cascade laser,the solid-state laser has the merits of high optical power,excellent beam quality,and wide tuning range.Here we present a long-wave,high-power,wide-tunable,single-longitudinal-mode solid-state laser used as light source in a PAS sensor for trace gas detection.The self-built solid-state laser had an emission wavelength of～2 μm with Tm:YAP crystal as the gain material,with an excellent wavelength and optical power stability as well as a high beam quality.The wide wavelength tuning range of 9.44 nm covers the absorption spectra of water and ammonia,with a maximum optical power of～130 mW,allowing dual gas detection with a single laser source.The solid-state laser was used as light source in three different photoacoustic detection techniques:standard PAS with microphone,and external-and intra-cavity quartz-enhanced photoacoustic spectroscopy(QEPAS),proving that solid-state laser is an attractive excitation source in photoacoustic spectroscopy.

    Pure-high-even-order dispersion bound solitons complexes in ultra-fast fiber lasers

    Ying HanBo GaoHonglin WenChunyang Ma...
    957-972页
    查看更多>>摘要：Temporal solitons have been the focus of much research due to their fascinating physical properties.These solitons can form bound states,which are fundamentally crucial modes in fiber laser and present striking analogies with their matter molecules counterparts,which means they have potential applications in large-capacity transmission and all-optical information storage.Although traditionally,second-order dispersion has been the dominant dispersion for conventional solitons,recent experimental and theoretical research has shown that pure-high-even-order dispersion(PHEOD)solitons with energy-width scaling can arise from the interaction of arbitrary negative-even-order dispersion and Kerr nonlinearity.Despite these advancements,research on the bound states of PHEOD solitons is currently non-existent.In this study,we obtained PHEOD bound solitons in a fiber laser using an intra-cavity spectral pulse shaper for high-order dispersion management.Specifically,we experimentally demonstrate the existence of PHEOD solitons and PHEOD bound solitons with pure-quartic,-sextic,-octic,and-decic dispersion.Numerical simulations corroborate these experimental observations.Furthermore,vibrating phase PHEOD bound soliton pairs,sliding phase PHEOD bound soliton pairs,and hybrid phase PHEOD bound tri-soliton are discovered and characterized.These results broaden the fundamental understanding of solitons and show the universality of multi-soliton patterns.

    Optical probing of ultrafast laser-induced solid-to-overdense-plasma transitions

    973-984页
    查看更多>>摘要：Understanding the solid target dynamics resulting from the interaction with an ultrashort laser pulse is a challenging fundamental multi-physics problem involving atomic and solid-state physics,plasma physics,and laser physics.Knowledge of the initial interplay of the underlying processes is essential to many applications ranging from low-power laser regimes like laser-induced ablation to high-power laser regimes like laser-driven ion acceleration.Accessing the properties of the so-called pre-plasma formed as the laser pulse's rising edge ionizes the target is complicated from the theoretical and experimental point of view,and many aspects of this laser-induced transition from solid to overdense plasma over picosecond timescales are still open questions.On the one hand,laser-driven ion acceleration requires precise control of the pre-plasma because the efficiency of the acceleration process crucially depends on the target properties at the arrival of the relativistic intensity peak of the pulse.On the other hand,efficient laser ablation requires,for example,preventing the so-called"plasma shielding".By capturing the dynamics of the initial stage of the interaction,we report on a detailed visualization of the pre-plasma formation and evolution.Nanometer-thin diamond-like carbon foils are shown to transition from solid to plasma during the laser rising edge with intensities＜1016 W/cm2.Single-shot near-infrared probe transmission measurements evidence sub-picosecond dynamics of an expanding plasma with densities above 1023 cm-3(about 100 times the critical plasma density).The complementarity of a solid-state interaction model and kinetic plasma description provides deep insight into the interplay of initial ionization,collisions,and expansion.
