This paper shows theoretical and experimental results of the electric field-induced second harmonic generation in a single metal-silicon nanostructure for an optical-induced control of the χ(2) susceptibility.
We investigate axially defocused images of a single fluorescent emitter near metallic nanostructure to explore distortion due to the emitter-localized surface plasmon interaction and retrieve information regarding precise emitter positions.
We report a universal paradigm for achieving a high-efficiency EP in the visible by leveraging interlayer loss to accurately control the interplay between the lossy structure and lightwaves.
An achromatic diffractive liquid crystal optics system has been demonstrated to overcome the longstanding chromatic aberration issue, which provides more compact optical components for a wide range of applications.
We present DEEP-squared, a machine learning model trained physics-informed to improve widefield two-photon imaging speed by nearly an order of magnitude for de-scattering with excitation pattering (DEEP).
We achieve milliwatt laser emissions at 1.06 µm wavelength from a 30 µm solid-state whispering-gallery-mode laser, constructed using Nd:YAG thin films obtained through carbon-implantation enhanced etching of a Nd:YAG crystal.
High security solid-state optical encryption is developed, based on fluorescent and phosphorescent dual-light-emitting MOFs in combination with 2D- and 3D-printing technologies.
We demonstrate the manipulation of nonlinear polaritons and their prolonged coherence by creating fully deterministic potential wells with the lithographic mesas to trap polaritons in a monolayer WS2 microcavity.
3D printing of a fiber-bound polymer-core/gold-shell spiral-grating conical tip that has 10% transmission efficiency, ~ 5 nm spatial resolution of optical near-field imaging, 20 dB signal-to-noise ratio, and fast scanning speed.
We present a chip-integrated Metasurface-based Full-Stokes Polarimetric Imaging sensor (MetaPolarIm) with ultra-compactness, record high measurement accuracy, dual color operation, and a field of view up to 40 degrees.
Optoelectronic performances of perovskite nanocrystals were improved by the introduction of new anchoring points and delocalized benzene rings. Corresponding LEDs achieved high EQE of 22.8% and low efficiency roll-off.
The first combination of chaos laser and Raman distributed optical fiber sensing breaks the physical bottleneck of spatial resolution, the optimal spatial resolution of the current kilometer-level sensing distance is achieved.
This work demonstrates Raman amplification at 2.2 μm and the extension for mid-infrared source generation via cascaded processes by making use of a highly nonlinear silicon core fiber platform.
We propose a deep self-learning approach driven by optical principles for fast and high-fidelity 3D isotropic resolution restoration for volumetric microscopy.
The spinor evolves along a direction perpendicular to synthetic magnetic field B and state vector S, resulting in Rabi oscillatory modes. Trajectories in phase matching and mismatching conditions are presented for positive and negative crystals.
