Abstract

Self-aligned Buried Crescent Heterostructure (BCH) semiconductor lasers and LEDs have been successfully developed as superb light sources for fiber optic communications. The fabrication and performance characteristics of these InGaAsP/InP lasers and LEDs are described. For lasers, the threshold currents as low as 10 mA and differential quantum efficiencies as high as 50% are achieved. For LEDs, the output powers at 150 mA are higher than 1 mW. Good far field patterns are obtained in both the LEDs and lasers. Measured I-V, L-I, spectrum and far field patterns are presented.
