    查看更多>>摘要：In recent years,the integration of deep learning techniques with biophotonic setups has opened new horizons in bioimaging.A compelling trend in this field involves deliberately compromising certain measurement metrics to engineer better bioimaging tools in terms of e.g.,cost,speed,and form-factor,followed by compensating for the resulting defects through the utilization of deep learning models trained on a large amount of ideal,superior or alternative data.This strategic approach has found increasing popularity due to its potential to enhance various aspects of biophotonic imaging.One of the primary motivations for employing this strategy is the pursuit of higher temporal resolution or increased imaging speed,critical for capturing fine dynamic biological processes.Additionally,this approach offers the prospect of simplifying hardware requirements and complexities,thereby making advanced imaging standards more accessible in terms of cost and/or size.This article provides an in-depth review of the diverse measurement aspects that researchers intentionally impair in their biophotonic setups,including the point spread function(PSF),signal-to-noise ratio(SNR),sampling density,and pixel resolution.By deliberately compromising these metrics,researchers aim to not only recuperate them through the application of deep learning networks,but also bolster in return other crucial parameters,such as the field of view(FOV),depth of field(DOF),and space-bandwidth product(SBP).Throughout this article,we discuss various biophotonic methods that have successfully employed this strategic approach.These techniques span a wide range of applications and showcase the versatility and effectiveness of deep learning in the context of compromised biophotonic data.Finally,by offering our perspectives on the exciting future possibilities of this rapidly evolving concept,we hope to motivate our readers from various disciplines to explore novel ways of balancing hardware compromises with compensation via artificial intelligence(AI).

    查看更多>>摘要：Quantum key distribution(QKD)enables the transmission of information that is secure against general attacks by eavesdroppers.The use of on-demand quantum light sources in QKD protocols is expected to help improve security and maximum tolerable loss.Semiconductor quantum dots(QDs)are a promising building block for quantum communication applications because of the deterministic emission of single photons with high brightness and low multiphoton contribution.Here we report on the first intercity QKD experiment using a bright deterministic single photon source.A BB84 protocol based on polarisation encoding is realised using the high-rate single photons in the telecommunication C-band emitted from a semiconductor QD embedded in a circular Bragg grating structure.Utilising the 79 km long link with 25.49 dB loss(equivalent to 130 km for the direct-connected optical fibre)between the German cities of Hannover and Braunschweig,a record-high secret key bits per pulse of 4.8 x 10-5 with an average quantum bit error ratio of～0.65％are demonstrated.An asymptotic maximum tolerable loss of 28.11 dB is found,corresponding to a length of 144 km of standard telecommunication fibre.Deterministic semiconductor sources therefore challenge state-of-the-art QKD protocols and have the potential to excel in measurement device independent protocols and quantum repeater applications.

    High brightness terahertz quantum cascade laser with near-diffraction-limited Gaussian beam

    2124-2130页
    查看更多>>摘要：High-power terahertz(THz)quantum cascade laser,as an emerging THz solid-state radiation source,is attracting attention for numerous applications including medicine,sensing,and communication.However,due to the sub-wavelength confinement of the waveguide structure,direct beam brightness upscaling with device area remains elusive due to several mode competition and external optical lens is normally used to enhance the THz beam brightness.Here,we propose a metallic THz photonic crystal resonator with a phase-engineered design for single mode surface emission over a broad area.The quantum cascade surface-emitting laser is capable of delivering an output peak power over 185 mW with a narrow beam divergence of 4.4°×4.4° at 3.88 THz.A high beam brightness of 1.6 × 107Wsr-1m-2 with near-diffraction-limited M2 factors of 1.4 in both vertical and lateral directions is achieved from a large device area of 1.6 × 1.6 mm2 without using any optical lenses.The adjustable phase shift between the lattices enables a stable and high-intensity surface emission over a broad device area,which makes it an ideal light extractor for large-scale THz emitters.Our research paves the way to high brightness solid-state THz lasers and facilitates new applications in standoff THz imaging,detection,and diagnosis.

    Single 5-nm quantum dot detection via microtoroid optical resonator photothermal microscopy

    查看更多>>摘要：Label-free detection techniques for single particles and molecules play an important role in basic science,disease diagnostics,and nanomaterial investigations.While fluorescence-based methods are tools for single molecule detection and imaging,they are limited by available molecular probes and photoblinking and photobleaching.Photothermal microscopy has emerged as a label-free imaging technique capable of detecting individual nanoabsorbers with high sensitivity.Whispering gallery mode(WGM)microresonators can confine light in a small volume for enhanced light-matter interaction and thus are a promising ultra-sensitive photothermal microscopy platform.Previously,microtoroid optical resonators were combined with photothermal microscopy to detect 250 nm long gold nanorods and 100nm long polymers.Here,we combine microtoroids with photothermal microscopy to spatially detect single 5 nm diameter quantum dots(QDs)with a signal-to-noise ratio exceeding 104.Photothermal images were generated by point-by-point scanning of the pump laser.Single particle detection was confirmed for 18 nm QDs by high sensitivity fluorescence imaging and for 5 nm QDs via comparison with theory.Our system demonstrates the capability to detect a minimum heat dissipation of 0.75 pW.To achieve this,we integrated our microtoroid based photothermal microscopy setup with a low amplitude modulated pump laser and utilized the proportional-integral-derivative controller output as the photothermal signal source to reduce noise and enhance signal stability.The heat dissipation of these QDs is below that from single dye molecules.We anticipate that our work will have application in a wide variety of fields,including the biological sciences,nanotechnology,materials science,chemistry,and medicine.

    2156-2167页
    查看更多>>摘要：Ptychographic extreme ultraviolet(EUV)diffractive imaging has emerged as a promising candidate for the next generationmetrology solutions in the semiconductor industry,as it can image wafer samples in reflection geometry at the nanoscale.This technique has surged attention recently,owing to the significant progress in high-harmonic generation(HHG)EUV sources and advancements in both hardware and software for computation.In this study,a novel algorithm is introduced and tested,which enables wavelength-multiplexed reconstruction that enhances the measurement throughput and introduces data diversity,allowing the accurate characterisation of sample structures.To tackle the inherent instabilities of the HHG source,a modal approach was adopted,which represents the cross-density function of the illumination by a series of mutually incoherent and independent spatial modes.The proposed algorithm was implemented on a mainstream machine learning platform,which leverages automatic differentiation to manage the drastic growth in model complexity and expedites the computation using GPU acceleration.By optimising over 200 million parameters,we demonstrate the algorithm's capacity to accommodate experimental uncertainties and achieve a resolution approaching the diffraction limit in reflection geometry.The reconstruction of wafer samples with 20-nm high patterned gold structures on a silicon substrate highlights our ability to handle complex physical interrelations involving a multitude of parameters.These results establish ptychography as an efficient and accurate metrology tool.

    Low cross-talk optical addressing of trapped-ion qubits using a novel integrated photonic chip

    2179-2191页
    查看更多>>摘要：Individual optical addressing in chains of trapped atomic ions requires the generation of many small,closely spaced beams with low cross-talk.Furthermore,implementing parallel operations necessitates phase,frequency,and amplitude control of each individual beam.Here,we present a scalable method for achieving all of these capabilities using a high-performance integrated photonic chip coupled to a network of optical fibre components.The chip design results in very low cross-talk between neighbouring channels even at the micrometre-scale spacing by implementing a very high refractive index contrast between the channel core and cladding.Furthermore,the photonic chip manufacturing procedure is highly fllexible,allowing for the creation of devices with an arbitrary number of channels as well as non-uniform channel spacing at the chip output.We present the system used to integrate the chip within our ion trap apparatus and characterise the performance of the full individual addressing setup using a single trapped ion as a light-field sensor.Our measurements showed intensity cross-talk below～10-3 across the chip,with minimum observed cross-talk as low as～10-5.
