SURFACE EMISSION SEMICONDUCTOR LASER AND METHOD OF FABRICATION

摘要

PROBLEM TO BE SOLVED: To provide a surface emission semiconductor laser in which the polarization direction of laser light can be controlled and a method of fabrication. SOLUTION: A semiconductor substrate 101 and a resonator 120 have a function for controlling the polarization direction of laser light. The semiconductor substrate 101 and the resonator 120 are bent and applied with anisotropic strain. The polarization direction of laser light in an active layer 105 can be controlled by the anisotropic strain.
