Patent JP-H03261190-A (JP)
Title: Bistable semiconductor laser
Inventor: ODAKAWA TETSUSHI
IPC: H01S5/00
Filed: 1990-03-12
Abstract: PURPOSE:To lower the carrier density in a saturable absorbing region in a state of electroluminescence and keep a differential gain and an absorption coefficient large, by making the band gap of an active layer in a saturable absorbing region layer than that of a gain region. CONSTITUTION:A gain region A having an optical gain by current injection and a saturable absorbing region B where few current is injected are provided on the same oscillation axis, and the band gap of an active layer 3B in the saturable absorbing region B is made layer than that of an active layer 3A in the gain region A. In wavelengths near to a peak gain in the gain region A a great, absorption can be seen in the saturable absorbing region B but in a little longer wavelengths the absorption coefficient becomes smaller. Accordingly, spontaneously emitted light having wavelengths longer than the gain peak is not absorbed very much in the saturable absorbing region B. This lowers the carrier density of the saturable absorbing region B, and keeps the differential gain and absorption coefficient large.
