Kerr nonlinearity-assisted quadratic microcomb
Generation of nonlinear frequency combs in χ(3) optical microresonators has attracted tremendous research interest during the last decade. Recently, realization of the microcomb owing to χ(2) optical nonlinearity in the microresonator promises new ...

Power scaling of continuous-wave, narrow-linewidth fiber lasers are limited by the onset of stimulated Brillouin scattering (SBS) which manifests at threshold as potentially damaging, peak power, backward propagating pulses.

Design and generation of structured array beams with shape-invariant properties
We theoretically propose and experimentally demonstrate a flexible approach to generate an arbitrary shape-invariant structured array beam during propagation with the prescribed intensity distribution.

A monolithic MQW InP-InGaAsP-Based optical comb generator [PDF]
We report the first demonstration of a monolithic optical-frequency comb generator. The device is based on multi-section quaternary/quaternary eight-quantum-well InP-InGaAsP material in a frequency-modulated (FM) laser design. The modulation is generated

Phase Modulation of Retro-Reflected Radar Echo Signal Using a Microstrip Van-Atta Array
Van-atta array is able to retro-reflect the incident signal back to the income direction and, thus, it can maintain a relatively larger radar cross-section (RCS) in a large range of incidence angles.

A New Method for Total Fat Detection in Raw Milk Based on Dual Low-Coherence Interferometer
The present work experimentally demonstrates a multimode fiber optic sensing setup for total fat detection in raw milk samples. The optical fiber arrangement incorporates a low-coherence Fabry−Perot cavity operating in dual response.

Electrical Phase Modulation Based on Mid‐Infrared Intersubband Polaritonic Metasurfaces
Electrically reconfigurable metasurfaces that overcome the static limitations in controlling the fundamental properties of scattered light are opening new avenues for functional flat optics. This work proposes and experimentally demonstrates electrically
