    Label-free biosensing with singular-phase-enhanced lateral position shift based on atomically thin plasmonic nanomaterials

    810-822页
    查看更多>>摘要：Rapid plasmonic biosensing has attracted wide attention in early disease diagnosis and molecular biology research.However,it was still challenging for conventional angle-interrogating plasmonic sensors to obtain higher sensitivity without secondary amplifying labels such as plasmonic nanoparticles.To address this issue,we developed a plasmonic biosensor based on the enhanced lateral position shift by phase singularity.Such singularity presents as a sudden phase retardation at the dark point of reflection from resonating plasmonic substrate,leading to a giant position shift on reflected beam.Herein,for the first time,the atomically thin layer of Ge2Sb2Te5(GST)on silver nanofilm was demonstrated as a novel phase-response-enhancing plasmonic material.The GST layer was not only precisely engineered to singularize phase change but also served as a protective layer for active silver nanofilm.This new configuration has achieved a record-breaking largest position shift of 439.3 μm measured in calibration experiments with an ultra-high sensitivity of 1.72 × 108 nm RIU-1(refractive index unit).The detection limit was determined to be 6.97 × 10-7 RIU with a 0.12 μm position resolution.Besides,a large figure of merit(FOM)of 4.54 × 1011 μm(RIU·°)-1 was evaluated for such position shift interrogation,enabling the labelfree detection of trace amounts of biomolecules.In targeted biosensing experiments,the optimized sensor has successfully detected small cytokine biomarkers(TNF-a and IL-6)with the lowest concentration of 1 × 10-16M.These two molecules are the key proinflammatory cancer markers in clinical diagnosis,which cannot be directly screened by current clinical techniques.To further validate the selectivity of our sensing systems,we also measured the affinity of integrin binding to arginylglycylaspartic acid(RGD)peptide(a key protein interaction in cell adhesion)with different Mn2+ion concentrations,ranging from 1 nM to 1 mM.

    Electro-optic 3D snapshot of a laser wakefield accelerated kilo-ampere electron bunch

    823-834页
    查看更多>>摘要：Laser wakefield acceleration,as an advanced accelerator concept,has attracted great attentions for its ultrahigh acceleration gradient and the capability to produce high brightness electron bunches.The three-dimensional(3D)density serves as an evaluation metric for the particle bunch quality and is intrinsically related to the applications of an accelerator.Despite its significance,this parameter has not been experimentally measured in the investigation of laser wakefield acceleration.We report on an electro-optic 3D snapshot of a laser wakefield electron bunch at a position outside the plasma.The 3D shape of the electron bunch was detected by simultaneously performing optical transition radiation imaging and electro-optic sampling.Detailed 3D structures to a few micrometer levels were reconstructed using a genetic algorithm.The electron bunch possessed a transverse size of less than 30 micrometers.The current profile shows a multi-peak structure.The main peak had a duration of＜10 fs and a peak current＞1 kA.The maximum electron 3D number density was～9 × 1021 m-3.This research demonstrates a feasible way of 3D density monitoring on femtosecond kilo-ampere electron bunches,at any position of a beam transport line for relevant applications.

    Metasurface array for single-shot spectroscopic ellipsometry

    Shun WenXinyuan XueShuai WangYibo Ni...
    835-842页
    查看更多>>摘要：Spectroscopic ellipsometry is a potent method that is widely adopted for the measurement of thin film thickness and refractive index.Most conventional ellipsometers utilize mechanically rotating polarizers and grating-based spectrometers for spectropolarimetric detection.Here,we demonstrated a compact metasurface array-based spectroscopic ellipsometry system that allows single-shot spectropolarimetric detection and accurate determination of thin film properties without any mechanical movement.The silicon-based metasurface array with a highly anisotropic and diverse spectral response is combined with iterative optimization to reconstruct the full Stokes polarization spectrum of the light reflected by the thin film with high fidelity.Subsequently,the film thickness and refractive index can be determined by fitting the measurement results to a proper material model with high accuracy.Our approach opens up a new pathway towards a compact and robust spectroscopic ellipsometry system for the high throughput measurement of thin film properties.

    NOON-state interference in the frequency domain

    843-851页
    查看更多>>摘要：The examination of entanglement across various degrees of freedom has been pivotal in augmenting our understanding of fundamental physics,extending to high dimensional quantum states,and promising the scalability of quantum technologies.In this paper,we demonstrate the photon number path entanglement in the frequency domain by implementing a frequency beam splitter that converts the single-photon frequency to another with 50％probability using Bragg scattering four-wave mixing.The two-photon NOON state in a single-mode fiber is generated in the frequency domain,manifesting the two-photon interference with two-fold enhanced resolution compared to that of single-photon interference,showing the outstanding stability of the interferometer.This successful translation of quantum states in the frequency domain will pave the way toward the discovery of fascinating quantum phenomena and scalable quantum information processing.

    Electro-optic tuning in composite silicon photonics based on ferroionic 2D materials

    852-864页
    查看更多>>摘要：Tunable optical materials are indispensable elements in modern optoelectronics,especially in integrated photonics circuits where precise control over the effective refractive index is essential for diverse applications.Two-dimensional materials like transition metal dichalcogenides(TMDs)and graphene exhibit remarkable optical responses to external stimuli.However,achieving distinctive modulation across short-wave infrared(SWIR)regions while enabling precise phase control at low signal loss within a compact footprint remains an ongoing challenge.In this work,we unveil the robust electro-refractive response of multilayer ferroionic two-dimensional CuCrP2S6(CCPS)in the near-infrared wavelength range.By integrating CCPS into silicon photonics(SiPh)microring resonators(MRR),we enhance light-matter interaction and measurement sensitivity to minute phase and absorption variations.Results show that electrically driven Cu ions can tune the effective refractive index on the order of 2.8 × 10-3 RIU(refractive index unit)while preserving extinction ratios and resonance linewidth.Notably,these devices exhibit low optical losses and excellent modulation efficiency of 0.25 V.cm with a consistent blue shift in the resonance wavelengths among all devices for either polarity of the applied voltage.These results outperform earlier findings on phase shifters based on TMDs.Furthermore,our study demonstrates distinct variations in electro-optic tuning sensitivity when comparing transverse electric(TE)and transverse magnetic™modes,revealing a polarization-dependent response that paves the way for diverse applications in light manipulation.The combined optoelectronic and ionotronic capabilities of two-terminal CCPS devices present extensive opportunities across several domains.Their potential applications range from phased arrays and optical switching to their use in environmental sensing and metrology,optical imaging systems,and neuromorphic systems in light-sensitive artificial synapses.
