Omnidirectional Reflector with Total Internal Reflective Interface for Light Extraction Enhancement of Solid‐State Light Source (Phys. Status Solidi A 5∕2019)

Abstract

Solid‐State Light Source In article number http://doi.wiley.com/10.1002/pssa.201700775 Kazuyuki Yamae, Hiroshi Fukshima, and Kozo Fujimoto develop novel omnidirectional reflector with total internal reflective interface (TI‐ODR) which realizes higher reflectance compared to conventional reflector for solid‐state light source (SSL). The authors then fabricate the TI‐ODR onto a gallium nitride (GaN) ‐ based light emitting device (LED) and obtain a light extraction efficiency enhancement factor of approximately 1.1.
