A space-variant information density three-dimensional display with ultrawide field of view is achieved by a large-scale 2D-metagrating complex, which shows great potential for portable electronic devices.
A photon-counting distributed free-space spectroscopy is proposed and demonstrated using lidar technique. It is suitable for remote spectrum analysis with range resolution over wide band.
Topological holographic quench dynamics in a synthetic frequency dimension studied in modulated ring system shows the universal bulk-surface duality with complete topological information being encoded in the single time variable.
A smart-scanning fluorescence microscope adapts its scanning scheme to the curved surface of embryonic cell sheets. This results in a considerable reduction in light dose without deterioration of the images.
An all-fiber based endoscopic probe using a double-core double-clad fiber demonstrates the potential for nonlinear imaging applications such as image-guided surgery and in vivo diagnostics.
Regulation of photovoltaic response in multiferroic oxide BFCNT/BFCO heterojunction black silicon photovoltaic devices by polarization and magnetization.
A monolithic InP/SOI platform with dislocation-free, site-controlled and in-plane InP sub-micron wire and large dimension InP membrane array selectively grown on (001) SOI platform.
Moderate light absorption by bio-tissue is conducive to the imaging performance. The second near-infrared window is perfected as 900–1880 nm, and 2080–2340 nm is proposed as the third near-infrared window.
A Non-line-of-sight reconstruction framework with collaborative regularization of the hidden scene and the signal is proposed to obtain albedo and surface normal of the targets with robustness to noise.
Spatiotemporal focusing of ultrafast laser pulses enable thin print layers for projection multiphoton lithography. Complex 3D microstructures are printed in a continuous manner at high print rates.
A general principle enabling the actuation of micro-objects on dry frictional surfaces based on opto-thermo-mechanical effects is established and two-dimensional spiral motions of gold plates on micro-fibers are experimentally demonstrated.
A versatile high precision metrology instrument has been developed that surpass the limits of existing metrology techniques and opens up new possibilities to develop next-generation super-polished X-ray mirrors.
A 15-user quantum secure direct communication (QSDC) network is experimentally demonstrated, and any two users can perform QSDC task over 40 kilometers of optical fiber.
An optical fiber biosensor displaying superfine plasmonic spectral combs and enhanced by conjugate-induced amplification enables the detection of environmental estrogens down to pg/mL estradiol equivalent concentration level.
