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.
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.
