摘要:
A surface emitting laser includes a stepped structure including portions having different thicknesses. The optical path length from a plane defined above the stepped structure and extending parallel to a base substrate to an interface between a front mirror and the stepped structure is set to a specific value in each of the portions of the stepped structure.
