High‐Order Nonlinear Frequency Conversion in Transparent Conducting Oxide Thin Films
Advanced Optical Materials, Volume 12, Issue 28, October 4, 2024.Subwavelength aluminum zinc oxide films are optically pumped near their epsilon‐near‐zero point, observing relatively efficient frequency up‐conversion reaching the seventh order. A modified hydrodynamic‐Maxwell model is used, accounting for linear and nonlinear dispersions, nonlocal effects, and nonlinearities across a broad spectral region, thus ...

Intrinsic nonlinear geometric phase in SHG from zincblende crystal symmetry media
Nanophotonics, Volume 13, Issue 18, Page 3321-3326, August 2024.Abstract We demonstrate that AlGaAs thin films and metasurfaces generate a distinct intrinsic nonlinear geometric phase in their second harmonic signals, differing significantly from previous studies on nonlinear dielectric, plasmonic, or hybrid metasurfaces.

Phase Noise in Real‐World Twin‐Field Quantum Key Distribution
Advanced Quantum Technologies, Volume 7, Issue 6, June 2024.This study explores the impact of various noise sources on twin‐field quantum key distribution (TF‐QKD) systems, focusing on phase noise from photon sources and fibers. Results show that different TF‐QKD protocols are similarly affected by phase noise.
