SEMICONDUCTOR LASER AND OPTICALLY-PUMPED SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor laser, having an improved lateral guide which is suitable for optical pumping of a quantum well structure 7 in the semiconductor laser, provided with a semiconductor substrate 1 having a periodical arrangement of a recess incoming portion 2 or formed by a periodical arrangement of a semiconductor area in the semiconductor substrate. SOLUTION: A beam generated by the semiconductor laser cannot be propagated in the periodical arrangement, and a resonator 3 of the semiconductor laser lacks periodical arrangement in the lateral direction.
