Paper Abstract

Shuji Nakamura predicted in his Nobel lecture that GaN-based blue laser diodes are the future of solid state lighting. However, GaN-lasers still exhibit less than 40% electrical-to-optical power conversion efficiency while some blue LEDs exceed 80% and some GaAs-based infrared lasers exceed 70%. This talk investigates the reasons behind the efficiency limitation of GaN-based lasers and proposes an improved efficiency analysis method.
