ABSTRACT:
A vertical cavity surface emitting laser includes an active layer between a first reflector and a second reflector and at least either the first reflector or the second reflector includes a two-dimensional photonic crystal. The two-dimensional photonic crystal has a structure106showing an ununiform effective refractive index distribution in the plane of the reflector to realize both a high reflectivity and transverse mode control at the same time.
