“…One of the major applications of lasers is in communications, as anticipated at the inception of laser research in the late 1950s [1] and evidenced by continued attention throughout the 1960s [2]. A major deterrent to the rapid development of optical communication during this period was the lack of a reliable low-loss transmission medium.…”

The characteristics of (GaAl)As double heterostructure stripe contact injection lasers as they relate to applications in fiber optic data transmission systems are reviewed. Tlie laser characteristics are treated as optical, electrical, thermal, and mechanical interfaces to the system in order to emphasize the necessity of designing devices as a functional part of a system or subsystem. It is concluded that the laser is generally well suited as an optical source in a card-mountahle hybrid module transmitter for data links up to a few km and -100 Mbitls data rates. Areas requiring further development include lowering of the laser threshold current, improving the modal stability, packaging the laser with electronics and fiber optic transmission lines, and improving the laser lifetime under varying ambient temperature conditions.
