    Waveguide-based augmented reality displays:a highlight

    Jannick P.RollandJeremy Goodsell
    10-12页
    查看更多>>摘要：Augmented reality(AR),which emerged in the 1960s,remains a focal point of interest given its capacity to overlay the real world with digitally presented information through optical combiners.The prevalent combiner,commonly known as the waveguide in the AR literature,is prized for its compact design and generous eyebox—essential elements in human-centric technology.Nonetheless,these combiners encounter unique challenges in meeting various other requirements of the human visual system.This paper highlights a recent review of technological advancements and presents a forward-looking perspective on the future of AR technology.

    Dynamics of self-hybridized exciton-polaritons in 2D halide perovskites

    Surendra B.AnantharamanJason LynchChristopher E.StevensChristopher Munley...
    13-22页
    查看更多>>摘要：Excitons,bound electron-hole pairs,in two-dimensional hybrid organic inorganic perovskites(2D HOIPs)are capable of forming hybrid light-matter states known as exciton-polaritons(E-Ps)when the excitonic medium is confined in an optical cavity.In the case of 2D HOIPs,they can self-hybridize into E-Ps at specific thicknesses of the HOIP crystals that form a resonant optical cavity with the excitons.However,the fundamental properties of these self-hybridized E-Ps in 2D HOIPs,including their role in ultrafast energy and/or charge transfer at interfaces,remain unclear.Here,we demonstrate that＞0.5 μm thick 2D HOIP crystals on Au substrates are capable of supporting multiple-orders of self-hybridized E-P modes.These E-Ps have high Q factors(＞100)and modulate the optical dispersion for the crystal to enhance sub-gap absorption and emission.Through varying excitation energy and ultrafast measurements,we also confirm energy transfer from higher energy E-Ps to lower energy E-Ps.Finally,we also demonstrate that E-Ps are capable of charge transport and transfer at interfaces.Our findings provide new insights into charge and energy transfer in E-Ps opening new opportunities towards their manipulation for polaritonic devices.

    Metal to insulator transition for conducting polymers in plasmonic nanogaps

    Yuling XiongRohit ChikkaraddyCharlie ReadmanShu Hu...
    23-32页
    查看更多>>摘要：Conjugated polymers are promising material candidates for many future applications in flexible displays,organic circuits,and sensors.Their performance is strongly affected by their structural conformation including both electrical and optical anisotropy.Particularly for thin layers or close to crucial interfaces,there are few methods to track their organization and functional behaviors.Here we present a platform based on plasmonic nanogaps that can assess the chemical structure and orientation of conjugated polymers down to sub-10 nm thickness using light.We focus on a representative conjugated polymer,poly(3,4-ethylenedioxythiophene)(PEDOT),of varying thickness(2-20 nm)while it undergoes redox in situ.This allows dynamic switching of the plasmonic gap spacer through a metal-insulator transition.Both dark-field(DF)and surface-enhanced Raman scattering(SERS)spectra track the optical anisotropy and orientation of polymer chains close to a metallic interface.Moreover,we demonstrate how this influences both optical and redox switching for nanothick PEDOT devices.

    Free-moving-state microscopic imaging of cerebral oxygenation and hemodynamics with a photoacoustic fiberscope

    Xiaoxuan ZhongYizhi LiangXiaoyu WangHaoying Lan...
    33-46页
    查看更多>>摘要：We report the development of a head-mounted photoacoustic fiberscope for cerebral imaging in a freely behaving mouse.The 4.5-gram imaging probe has a 9-pm lateral resolution and 0.2-Hz frame rate over a 1.2-mm wide area.The probe can continuously monitor cerebral oxygenation and hemodynamic responses at single-vessel resolution,showing significantly different cerebrovascular responses to external stimuli under anesthesia and in the freely moving state.For example,when subjected to high-concentration CO2 respiration,enhanced oxygenation to compensate for hypercapnia can be visualized due to cerebral regulation in the freely moving state.Comparative studies exhibit significantly weakened compensation capabilities in obese rodents.This new imaging modality can be used for investigating both normal and pathological cerebrovascular functions and shows great promise for studying cerebral activity,disorders and their treatments.

    Single-emitter super-resolved imaging of radiative decay rate enhancement in dielectric gap nanoantennas

    R.Margoth Córdova-CastroBart van DamAlberto LauriStefan A.Maier...
    47-54页
    查看更多>>摘要：High refractive index dielectric nanoantennas strongly modify the decay rate via the Purcell effect through the design of radiative channels.Due to their dielectric nature,the field is mainly confined inside the nanostructure and in the gap,which is hard to probe with scanning probe techniques.Here we use single-molecule fluorescence lifetime imaging microscopy(smFLIM)to map the decay rate enhancement in dielectric GaP nanoantenna dimers with a median localization precision of 14 nm.We measure,in the gap of the nanoantenna,decay rates that are almost 30 times larger than on a glass substrate.By comparing experimental results with numerical simulations we show that this large enhancement is essentially radiative,contrary to the case of plasmonic nanoantennas,and therefore has great potential for applications such as quantum optics and biosensing.

    Ultrahigh-fidelity spatial mode quantum gates in high-dimensional space by diffractive deep neural networks

    Qianke WangJun LiuDawei LyuJian Wang...
    55-67页
    查看更多>>摘要：While the spatial mode of photons is widely used in quantum cryptography,its potential for quantum computation remains largely unexplored.Here,we showcase the use of the multi-dimensional spatial mode of photons to construct a series of high-dimensional quantum gates,achieved through the use of diffractive deep neural networks(D2NNs).Notably,our gates demonstrate high fidelity of up to 99.6(2)％,as characterized by quantum process tomography.Our experimental implementation of these gates involves a programmable array of phase layers in a compact and scalable device,capable of performing complex operations or even quantum circuits.We also demonstrate the efficacy of the D2NN gates by successfully implementing the Deutsch algorithm and propose an intelligent deployment protocol that involves self-configuration and self-optimization.Moreover,we conduct a comparative analysis of the D2NN gate's performance to the wave-front matching approach.Overall,our work opens a door for designing specific quantum gates using deep learning,with the potential for reliable execution of quantum computation.
