Light extraction efficiency is key to the performance of solid‐state light sources such as the light‐emitting diode. The reflectance of the bottom mirror has a significant impact on the light extraction efficiency because a large difference in the refractive index between the light source and air leads to multiple internal reflections and optical loss. Therefore, efficiency can be drastically improved...
Solid‐State Light Source
In article number 1700775 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)...
