High-speed InGaAsP constricted-mesa lasers.
01 January 1986
Recently, the bandwidths of semiconductor lasers, detectors and optical transmission systems have been dramatically increased. The considerations used to achieve a record 26.5 GHz bandwidth in a 1.3micron InGaAsP laser at -60C are described here. The small-signal modulation characteristics of a number of different laser structures are compared. Several large-signal modulation experiments are described with emphasis on the laser response to 8 Gb/s modulation.
