Abstract
Reductions in power consumption and improvements in reliability have made AlGaAs stripe-contact heterojunction lasers well suited for many fiber optic data systems of present interest. Although the beam pattern of some of these lasers is in the form of a stable single lobe, instabilities in the lateral direction are often observed, and require further attention for fibers with small acceptance angles. For long-distance, high-data-rate fiber systems, heterojunction lasers with emission wavelengths beyond 1 ptm are being developed. Such lasers of InGaAsP/InP have many attractive properties, but suffer from carrier leakage at short wavelengths (1.0-1.2 µm) and elevated temperatures.
