Enhanced vertical extraction efficiency from a thin-film InGaN/GaN photonic crystal light-emitting diodes

Abstract

An InGaN/GaN thin-film light-emitting diode with the photonic crystal (PhC) on the surface and a TiO(2)/SiO(2) omnidirectional reflector on the bottom was fabricated and found the line-width emission spectrum of 5 nm by the PhC. (C) 2007 Optical Society of America
