A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.230005 overviews how GaN-based LED achieves high rate Wavelength division multiplexing visible light communication system with ...

A new semipolar InGaN LED with an integrated metasurface produces circularly polarized light at 68% conversion efficiency, surpassing the 50% theoretical limit. By combining a semipolar InGaN ...

Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip.

They’re consistently popular with the readers, which is admittedly part of my (and EDN’s) motivation to continue doing them. But I personally also find them fascinating; inevitably I come across at ...
