ABSTRACT:
A VCSEL which can be easily manufactured and can selectively suppress only high-order transverse mode oscillation is provided. The VCSEL includes a resonator, a first current confinement layer, and a second current confinement layer. The resonator includes an active layer having a light emitting region, and a pair of first multilayer reflector and a second multilayer reflector provided with the active layer in between, and resonate is generated in a given wavelength. The first current confinement layer has a current injection region is a region corresponding to the light emitting region, and is formed at a region including an antinode of a standing wave. The second current confinement layer has a current injection region with a diameter smaller than a diameter of the first current injection region and is formed at a region including a node standing wave.
