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.
The application of light-emitting diodes (LEDs) in display and lighting has been a topic of extensive research and development since the past decade 1. Especially, the development of white light LEDs ...
Gallium nitride (GaN) materials have been applied in optoelectronic devices such as light-emitting diodes (LEDs), laser diodes (LDs) 1, and vertical cavity surface emitting lasers (VCSELs) 2, 3.
