Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1986-09-03
Abstract: PURPOSE:To generate stable self-exciting vibration, to implement a low noise characteristic and to make it possible to maintain basic lateral-mode oscillation, by setting special relationships between refractive indexes of first-fifth clad layers, and making all refractive indexes smaller than the refractive index of an active layer. CONSTITUTION:On an N-type GaAs substrate 10, the following layers are continuously grown by an MOCVD method: an N-type Al0.45Ga0.55As first clad layer 11; a N-type Al0.15Ga0.85As active layer 12; a P-type Al0.45Ga0.55As second clad layer 13; a P-type Al0.36Ga0.64As third clad layer 14; an N-type Al0.5Ga0.5As fourth clad layer 15; and an N-type GaAs block layer 16. After a photoresist film 18 is removed, a groove is formed. A P-type Al0.4Ga0.6As fifth clad layer 20 and a P-type GaAs cap layer 21 are continuously grown. Refractive indexes n1-n5 of the first-fifth clad layers are all smaller than the refractive index of the active layer 12. Relationships n1<N3, n2<N3, n4<N3 and n4<N5 are obtained. Thus, stable basic lateral mode oscillation can be maintained up to high optical output power. Self-exciting vibration is generated. Since the allowance range of the condition is broad, the low-noise characteristic can be readily obtained.
