摘要：

The growth of InGaN/AlGaN multiple quantum wells (MQWs) structures is highly effective for realizing high quality semipolar (20 (2) over bar1). active regions for green light emitting diodes (LEDs) and laser diodes (LDs) The use of AlGaN barriers significantly improved internal quantum efficiencies and the uniformity of the emission compared to InGaN or GaN barriers 516 nm lasing wavelength was demonstrated on semipolar (20 (2) over bar1) GaN substrates by introducing three periods InGaN/AlGaN MQWs and the AlGaN-cladding-free optical waveguide consisting of GaN cladding and InGaN guiding layers (C) 2010 The Japan Society of Applied Physics
