Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy
Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm −1 precision).

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Ge substitution in Li6+xGexAs1‐xS5Br expands the lattice, redistributes Li+, and enhances intercage diffusion, increasing ionic conductivity 6‐fold to 12.7 mS/cm at x = 0.5. Li6.5As0.5Ge0.5S5Br also shows improved air stability, linking the lithium substructure to fast, stable ion transport in thioarsenate argyrodites. ABSTRACT Lithium argyrodite solid
