It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

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 ...

For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ — injecting electric current into semiconductors — hasn’t ...
