Electro-optic tuning in composite silicon photonics based on ferroionic 2D materials
The integration of transition metal thio/selenophosphates (TPS) like CuInPS and CuCrPS onto Silicon Photonics marks a significant advancement in optical devices. This innovation provides precise control over refractive index, minimizes optical losses, enhances modulation efficiency, and reduces the footprint for next-generation optoelectronics.

NOON-state interference in the frequency domain
We report the NOON-state interference in the frequency domain. Two photons with distinct colors, blue and red, are injected into an interferometer constructed with two frequency beam splitters. The resultant interference pattern is then observed.
