    Non-convex optimization for inverse problem solving in computer-generated holography

    1464-1486页
    查看更多>>摘要：Computer-generated holography is a promising technique that modulates user-defined wavefronts with digital holograms.Computing appropriate holograms with faithful reconstructions is not only a problem closely related to the fundamental basis of holography but also a long-standing challenge for researchers in general fields of optics.Finding the exact solution of a desired hologram to reconstruct an accurate target object constitutes an ill-posed inverse problem.The general practice of single-diffraction computation for synthesizing holograms can only provide an approximate answer,which is subject to limitations in numerical implementation.Various non-convex optimization algorithms are thus designed to seek an optimal solution by introducing different constraints,frameworks,and initializations.Herein,we overview the optimization algorithms applied to computer-generated holography,incorporating principles of hologram synthesis based on alternative projections and gradient descent methods.This is aimed to provide an underlying basis for optimized hologram generation,as well as insights into the cutting-edge developments of this rapidly evolving field for potential applications in virtual reality,augmented reality,head-up display,data encryption,laser fabrication,and metasurface design.

    Ultrasound sensing with optical microcavities

    1487-1511页
    查看更多>>摘要：Ultrasound sensors play an important role in biomedical imaging,industrial nondestructive inspection,etc.Traditional ultrasound sensors that use piezoelectric transducers face limitations in sensitivity and spatial resolution when miniaturized,with typical sizes at the millimeter to centimeter scale.To overcome these challenges,optical ultrasound sensors have emerged as a promising alternative,offering both high sensitivity and spatial resolution.In particular,ultrasound sensors utilizing high-quality factor(Q)optical microcavities have achieved unprecedented performance in terms of sensitivity and bandwidth,while also enabling mass production on silicon chips.In this review,we focus on recent advances in ultrasound sensing applications using three types of optical microcavities:Fabry-Perot cavities,n-phase-shifted Bragg gratings,and whispering gallery mode microcavities.We provide an overview of the ultrasound sensing mechanisms employed by these microcavities and discuss the key parameters for optimizing ultrasound sensors.Furthermore,we survey recent advances in ultrasound sensing using these microcavity-based approaches,highlighting their applications in diverse detection scenarios,such as photoacoustic imaging,ranging,and particle detection.The goal of this review is to provide a comprehensive understanding of the latest advances in ultrasound sensing with optical microcavities and their potential for future development in high-performance ultrasound imaging and sensing technologies.

    High-power,electrically-driven continuous-wave 1.55-μm Si-based multi-quantum well lasers with a wide operating temperature range grown on wafer-scale InP-on-Si(100)heterogeneous substrate

    查看更多>>摘要：A reliable,efficient and electrically-pumped Si-based laser is considered as the main challenge to achieve the integration of all key building blocks with silicon photonics.Despite the impressive advances that have been made in developing 1.3-μm Si-based quantum dot(QD)lasers,extending the wavelength window to the widely used 1.55-μm telecommunication region remains difficult.In this study,we develop a novel photonic integration method of epitaxial growth of Ⅲ-Ⅴ on a wafer-scale InP-on-Si(100)(InPOS)heterogeneous substrate fabricated by the ion-cutting technique to realize integrated lasers on Si substrate.This ion-cutting plus epitaxial growth approach decouples the correlated root causes of many detrimental dislocations during heteroepitaxial growth,namely lattice and domain mismatches.Using this approach,we achieved state-of-the-art performance of the electrically-pumped,continuous-wave(CW)1.55-μm Si-based laser with a room-temperature threshold current density of 0.65 kA/cm-2,and output power exceeding 155 mW per facet without facet coating in CW mode.CW lasing at 120 ℃ and pulsed lasing at over 130 ℃ were achieved.This generic approach is also applied to other material systems to provide better performance and more functionalities for photonics and microelectronics.

    Strong nonlinear optical processes with extraordinary polarization anisotropy in inversion-symmetry broken two-dimensional PdPSe

    Song ZhuRuihuan DuanXiaodong XuFangyuan Sun...
    1524-1533页
    查看更多>>摘要：Nonlinear optical activities,especially second harmonic generation(SHG),are key phenomena in inversion-symmetry-broken two-dimensional(2D)transition metal dichalcogenides(TMDCs).On the other hand,anisotropic nonlinear optical processes are important for unique applications in nano-nonlinear photonic devices with polarization functions,having become one of focused research topics in the field of nonlinear photonics.However,the strong nonlinearity and strong optical anisotropy do not exist simultaneously in common 2D materials.Here,we demonstrate strong second-order and third-order susceptibilities of 64pmN and 6.2×10-19 m2/V2,respectively,in the even-layer PdPSe,which has not been discovered in other common TMDCs(e.g.,MoS2).Strikingly,it also simultaneously exhibited strong SHG anisotropy with an anisotropic ratio of～45,which is the largest reported among all 2D materials to date,to the best of our knowledge.In addition,the SHG anisotropy ratio can be harnessed from 0.12 to 45(375 times)by varying the excitation wavelength due to the dispersion of x(2)values.As an illustrative example,we further demonstrate polarized SHG imaging for potential applications in crystal orientation identification and polarization-dependent spatial encoding.These findings in 2D PdPSe are promising for nonlinear nanophotonic and optoelectronic applications.

    Brillouin expanded time-domain analysis based on dual optical frequency combs

    1534-1544页
    查看更多>>摘要：Brillouin Optical Time-Domain Analysis(BOTDA)is a widely-used distributed optical fiber sensing technology employing pulse-modulated pump waves for local information retrieval of the Brillouin gain or loss spectra.The spatial resolution of BOTDA systems is intrinsically linked to pulse duration,so high-resolution measurements demand high electronic bandwidths inversely proportional to the resolution.This paper introduces Brillouin Expanded Time-Domain Analysis(BETDA)as a modified BOTDA system,simultaneously achieving high spatial resolution and low detection bandwidth.Utilizing two optical frequency combs(OFCs)with different frequency intervals as pump and probe,local Brillouin gain spectra are recorded by their spectral beating traces in an expanded time domain.A 2-cm-long hotspot located in a 230 m single-mode fiber is successfully measured in the time domain with a detection bandwidth of less than 100 kHz using dual OFCs with tailored spectral phase,line spacing,and bandwidth.

    Enhanced photothermoelectric conversion in self-rolled tellurium photodetector with geometry-induced energy localization

    Jiayuan HuangChunyu YouBinmin WuYunqi Wang...
    1545-1556页
    查看更多>>摘要：Photodetection has attracted significant attention for information transmission.While the implementation relies primarily on the photonic detectors,they are predominantly constrained by the intrinsic bandgap of active materials.On the other hand,photothermoelectric(PTE)detectors have garnered substantial research interest for their promising capabilities in broadband detection,owing to the self-driven photovoltages induced by the temperature differences.To get higher performances,it is crucial to localize light and heat energies for efficient conversion.However,there is limited research on the energy conversion in PTE detectors at micro/nano scale.In this study,we have achieved a two-order-of-magnitude enhancement in photovoltage responsivity in the self-rolled tubular tellurium(Te)photodetector with PTE effect.Under illumination,the tubular device demonstrates a maximum photovoltage responsivity of 252.13 VW-1 and a large detectivity of 1.48 x 1011 Jones.We disclose the mechanism of the PTE conversion in the tubular structure with the assistance of theoretical simulation.In addition,the device exhibits excellent performances in wide-angle and polarization-dependent detection.This work presents an approach to remarkably improve the performance of photodetector by concentrating light and corresponding heat generated,and the proposed self-rolled devices thus hold remarkable promises for next-generation on-chip photodetection.
