    1008-1011页
    查看更多>>摘要：An ultra-simple and miniaturized spectrometer using an arbitrarily shaped pinhole as diffraction element reconstructs a broadband spectrum from the information of diffraction of monochromatic radiation by clever computational reconstruction algorithms.This circumvents complex calibration procedures and paves the way to cost-effective on-chip spectrometers combining fast acquisition without significant loss in spectral resolution.

    Ultra-simplified diffraction-based computational spectrometer

    1022-1031页
    查看更多>>摘要：Miniaturizing spectrometers for compact and cost-effective mobile platforms is a major challenge in current spectroscopy research,where conventional spectrometers are impractical due to their bulky footprint.Existing miniaturized designs primarily rely on precalibrated response functions of nanophotonic structures to encode spectral information captured in a snapshot by detector arrays.Accurate spectrum reconstruction is achieved through computational techniques,but this requires precise component design,high-precision fabrication,and calibration.We propose an ultra-simplified computational spectrometer that employs a one-to-broadband diffraction decomposition strategy facilitated by a numerical regularized transform that depends only on the spectrum of the diffracted radiation.The key feature of our design is the use of a simple,arbitrarily shaped pinhole as the partial disperser,eliminating the need for complex encoding designs and full spectrum calibration.Our spectrometer achieves a reconstructed spectral peak location accuracy of better than 1 nm over a 200 nm bandwidth and excellent resolution for peaks separated by 3 nm in a bimodal spectrum,all within a compact footprint of under half an inch.Notably,our approach also reveals a breakthrough in broadband coherent diffractive imaging without requiring any prior knowledge of the broadband illumination spectrum,assumptions of non-dispersive specimens,or correction for detector quantum efficiency.

    Strong-field photoelectron holography in the subcycle limit

    1032-1040页
    查看更多>>摘要：Strong-field photoelectron holography is promising for the study of electron dynamics and structure in atoms and molecules,with superior spatiotemporal resolution compared to conventional electron and X-ray diffractometry.However,the application of strong-field photoelectron holography has been hindered by inter-cycle interference from multicycle fields.Here,we address this challenge by employing a near-single-cycle field to suppress the inter-cycle interference.We observed and separated two distinct holographic patterns for the first time.Our measurements allow us not only to identify the Gouy phase effect on electron wavepackets and holographic patterns but also to correctly extract the internuclear separation of the target molecule from the holographic pattern.Our work leads to a leap jump from theory to application in the field of strong-field photoelectron holography-based ultrafast imaging of molecular structures.

    Entangled photon pair generation in an integrated SiC platform

    1041-1046页
    查看更多>>摘要：Entanglement plays a vital role in quantum information processing.Owing to its unique material properties,silicon carbide recently emerged as a promising candidate for the scalable implementation of advanced quantum information processing capabilities.To date,however,only entanglement of nuclear spins has been reported in silicon carbide,while an entangled photon source,whether it is based on bulk or chip-scale technologies,has remained elusive.Here,we report the demonstration of an entangled photon source in an integrated silicon carbide platform for the first time.Specifically,strongly correlated photon pairs are efficiently generated at the telecom C-band wavelength through implementing spontaneous four-wave mixing in a compact microring resonator in the 4H-silicon-carbide-on-insulator platform.The maximum coincidence-to-accidental ratio exceeds 600 at a pump power of 0.17 mW,corresponding to a pair generation rate of(9±1)× 103 pairs/s.Energy-time entanglement is created and verified for such signal-idler photon pairs,with the two-photon interference fringes exhibiting a visibility larger than 99％.The heralded single-photon properties are also measured,with the heralded g(2)(0)on the order of 10-3,demonstrating the SiC platform as a prospective fully integrated,complementary metal-oxide-semiconductor compatible single-photon source for quantum applications.

    Wireless sequential dual light delivery for programmed PDT in vivo

    1047-1061页
    查看更多>>摘要：Using photodynamic therapy(PDT)to treat deep-seated cancers is limited due to inefficient delivery of photosensitizers and low tissue penetration of light.Polymeric nanocarriers are widely used for photosensitizer delivery,while the self-quenching of the encapsulated photosensitizers would impair the PDT efficacy.Furthermore,the generated short-lived reactive oxygen spieces(ROS)can hardly diffuse out of nanocarriers,resulting in low PDT efficacy.Therefore,a smart nanocarrier system which can be degraded by light,followed by photosensitizer activation can potentially overcome these limitations and enhance the PDT efficacy.A light-sensitive polymer nanocarrier encapsulating photosensitizer(RB-M)was synthesized.An implantable wireless dual wavelength microLED device which delivers the two light wavelengths sequentially was developed to programmatically control the release and activation of the loaded photosensitizer.Two transmitter coils with matching resonant frequencies allow activation of the connected LEDs to emit different wavelengths independently.Optimal irradiation time,dose,and RB-M concentration were determined using an agent-based digital simulation method.In vitro and in vivo validation experiments in an orthotopic rat liver hepatocellular carcinoma disease model confirmed that the nanocarrier rupture and sequential low dose light irradiation strategy resulted in successful PDT at reduced photosensitizer and irradiation dose,which is a clinically significant event that enhances treatment safety.

    Omnidirectional color wavelength tuning of stretchable chiral liquid crystal elastomers

    查看更多>>摘要：Wavelength-tunable structural colors using stimuli-responsive materials,such as chiral liquid crystals(CLCs),have attracted increasing attention owing to their high functionality in various tunable photonic applications.Ideally,on-demand omnidirectional wavelength control is highly desirable from the perspective of wavelength-tuning freedom.However,despite numerous previous research efforts on tunable CLC structural colors,only mono-directional wavelength tuning toward shorter wavelengths has been employed in most studies to date.In this study,we report the ideally desired omnidirectional wavelength control toward longer and shorter wavelengths with significantly improved tunability over a broadband wavelength range.By using areal expanding and contractive strain control of dielectric elastomer actuators(DEAs)with chiral liquid crystal elastomers(CLCEs),simultaneous and omnidirectional structural color-tuning control was achieved.This breakthrough in omnidirectional wavelength control enhances the achievable tuning freedom and versatility,making it applicable to a broad range of high-functional photonic applications.

    Ionizing terahertz waves with 260 MV/cm from scalable optical rectification

    Hyeongmun KimChul KangDogeun JangYulan Roh...
    1075-1087页
    查看更多>>摘要：Terahertz(THz)waves,known as non-ionizing radiation owing to their low photon energies,can actually ionize atoms and molecules when a sufficiently large number of THz photons are concentrated in time and space.Here,we demonstrate the generation of ionizing,multicycle,15-THz waves emitted from large-area lithium niobate crystals via phase-matched optical rectification of 150-terawatt laser pulses.A complete characterization of the generated THz waves in energy,pulse duration,and focal spot size shows that the field strength can reach up to 260 megavolts per centimeter.In particular,a single-shot THz interferometer is employed to measure the THz pulse duration and spectrum with complementary numerical simulations.Such intense THz pulses are irradiated onto various solid targets to demonstrate THz-induced tunneling ionization and plasma formation.This study also discusses the potential of nonperturbative THz-driven ionization in gases,which will open up new opportunities,including nonlinear and relativistic THz physics in plasma.
