Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares.

In order to improve the information transmission capability of photonic devices, multiplexing technologies such as wavelength division multiplexing (WDM), polarization division multiplexing (PDM) and ...

Toward developing chip-integrated and miniaturized nanophotonic devices, the incorporation of metasurfaces onto optical waveguides has attracted widespread attention as a compact platform for ...

Fujitsu has developed a mmWave chip that supports multibeam multiplexing (excluding polarization multiplexing) for use in the radio units (RUs) of 5G base stations. The technology enables up to four ...
