Title: Optical semiconductor device
Inventor: SHINADA HIDETOSHI
IPC: H01S5/30
Filed: 1987-10-28
Abstract: PURPOSE:To stabilize a lateral mode by continuously altering an injected carrier density distribution between a light incident side and a light emitting side. CONSTITUTION:Since carrier consumptions are different with places in an active region 16, it is necessary to form the carrier density distribution at least similar to photon density distribution. Accordingly, a current value between two electrodes 18 and 20 is continuously varied between an incident end face 22 and an emitting side end face 24. That is, while a current value which is applied to one electrode 18 (20) as a base remains constant, a conductivity between the electrodes 18 and 20 is varied thereby to alter the current density in an active region 16. Thus, the carrier density distribution can be continuously varied in terms of an arbitrary curve from the incident side end face to the emitting side end face, thereby controlling the carrier density in a state that a lateral mode is stabilized.
