Title: Quantum-well type semiconductor laser
Inventor: KITAMURA MITSUHIRO
IPC: H01S5/00
Filed: 1987-04-28
Abstract: PURPOSE:To obtain excellent reliability and manufacturing yield and high performance by making the well layer in an active layer which makes light emitting recombination thicker near the axis of a laser resonator. CONSTITUTION:A quantum well type semiconductor laser has an active layer 5 made of a semiconductor thin film on a semiconductor substrate 1 and the well layer in the active layer 5 which makes light emitting recombination is made thicker near the axis of a laser resonator. That is, if the thickness of an n-InP butter layer 4 is made approx. 0.4mum-0.5mum at a groove, the active layer 5 can be made thicker at the center and thinner at the periphery. This can effectively concentrate an implanting carrier at the center of the active layer 5 and the leakage of the carrier to a transverse direction is greatly restrained. In the manufacture of the quantum-well type semiconductor laser, a process of regrowth after the active layer 5 is grown is also unnecessary so reliability and manufacturing yield are greatly improved.
