SEMICONDUCTOR LASER DEVICE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To control the space of a light emission point of each semiconductor laser chip by self-alignment in a semiconductor laser element array which is subjected to hybrid integration.

SOLUTION: The semiconductor laser device 100 is formed of silicon, for example, and has a substrate 10 having a first recess 10a, and a second recess 10b formed on a major surface apart from each other. A first semiconductor laser element 11 which is made to be a functional block emitting an infrared laser beam is set in the first recess 10a, and a second semiconductor laser element 12 which is made to be a functional block emitting a red laser beam is set in the second recess 10b.
