Harmonic generation in wide bandgap semiconductors and dielectrics has attracted a surge of interest as a compact solid-state light sour...

GeSn alloy has emerged as an attractive active material for Si-based mid-infrared (MIR) lasers due to its direct bandgap nature at higher...

Polycrystalline Ce3+-doped fluorapatite (Ce:FAP) transparent ceramics with fine microstructures were fabricated through liquid-phase syn...

We previously reported a scheme for collinear emission of high-efficiency and ultra-broadband photon pairs using chirped quasi-phase mat...

We propose a simple scheme of degenerate spontaneous parametric down-conversion (SPDC) in nonlinear metasurfaces or photonic crystal slab...
