Abstract
A surface emitting laser having a mesa structure includes an off-orientation substrate, a bottom reflection mirror, an active layer, a current confinement layer, a top reflection mirror, and a surface-relief structure. The central axis of a high-reflectivity region of the surface-relief structure and the central axis of the mesa structure do not coincide with each other.
