Outlook brightens for semiconductor lasers
Abstract
The theory and development of semiconductor diode lasers are reviewed. Single-mode lasers, monochromatic lasers, high-power lasers, the larger wavelengths afforded by quaternary devices, and the possibility of shorter wavelengths through use of a strained-layer superlattice structure are considered. It is noted that mass markets are needed for the continued development of such diode laser applications as optical recording and audiodisc playback, optical data recording and storage, and printing technologies. Advances in laser diode research have been most remarkable in the field of fiber optic communications where third-generation monomode systems using 1.3-micron wavelength lasers have been installed as the backbones for nationwide networks.
