Title: Semiconductor laser and method of manufacturing the same
Inventor: OKUDA HAJIME
IPC: H01S5/065
Filed: 2000-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser which can self-oscillate more stably at a low threshold value in a high temperature region than the conventional one and also provide a method of manufacturing the same. SOLUTION: A saturable absorption layer is disposed just under a current block layer and is made of such a material that has an etching rate sufficiently lower than that of the current block layer. Consequently, the structure of the semiconductor laser can be simplified, the current block layer can be processed easily and precisely, and an unwanted light absorption can be prevented which could occur when a separate etching stop layer is formed. By forming the saturable absorption layer from a multiple quantum well, the band gap energy of a well layer and the energy of light emitted from an active layer can be nearly the same, thereby stably making a saturable absorption. A 'deviation' of a lattice constant of the well layer can be lessened by adjusting the composition of a barrier layer.
