Enhancing light-matter interaction in 2D semiconductors coupled to Mie-resonant dielectric nanoantennas leads to the suppression of exciton-exciton annihilation, overcoming a fundamental limit for light emission in atomically thin materials.
By utilizing nanophotonic inverse-designed Fabry-Pérot cavities in silicon carbide, the first experimental realization of inverse design in quantum and nonlinear light generation is demonstrated.
The intense and flat ultraviolet-visible-infrared full-spectrum laser is a revolutionary tool that enables optical spectroscopy to simultaneously resolve ultrafast dynamics of multiple physical, chemical, and biological processes of a sample.
New speckle diffraction tomography demonstrates high-resolution refractive index mapping of thick scattering tissue, red blood cell imaging behind turbid layers, and nanoscale features in the cornea using spatiotemporal gating and inverse-scattering model.
Direct integration of an electro-optic modulator device on the endface of a single-mode fiber jumper for coupling-free treatments, dual-band operations (telecom O/S band) and high-speed modulations (~1 GHz).
Robot-compatible liquid sample setup for a fully-automated, μs-resolved Small-angle X-ray Photon Correlation Spectroscopy (SA-XPCS) workflow that can enable autonomous designs of complex fluids.
Under spatially incoherent illumination, a diffractive optical processor with sufficient degrees of freedom (N) can perform any arbitrary linear intensity transformation between an input and an output field-of-view (FOV).
The formation of solitons of topological origin is observed on disclination cores of pentagonal and heptagonal disclination arrays. Nonlinearity profoundly affects localization of such solitons that form as exceptionally robust objects in topological gap.
We propose an innovative optofluidic system, employing an all-dielectric quasi-BIC metasurface, that achieves subwavelength scale optical heating and fluid motion control via precisely tuning wavelengths within several nanometers range. Long-range transport and rapid assembly of nanoparticles are presented.
Impacts of air pollution and meteorological conditions on dry eye disease among residents in a northeastern Chinese metropolis: A six-year crossover study in a cold region.
We investigate the ultrafast optoelectronic response of semiconducting perovskite in an optically transparent terahertz cavity. Despite apparent polariton formation and strong electron-phonon coupling, the cavity-coupled material properties remain unchanged.
This work investigates the optical nonlinearities of quantum-dot mode-locked lasers and demonstrates how to generate the amplitude-modulated and the frequency-modulated comb independently from a single device.
Intervalence charge transfer (IVCT) for NIR-II luminescence was first reported in heavy Cr3+ doped LaMgGa11O19:Cr3+. The luminescence exhibits anti-thermal quenching behavior (432% @ 290 K), capable of NIR-II spectroscopy applications.
