Abstract:
1. A surface emitting laser device, comprising: a first resonance region that includes an active layer and spacer layers provided on two sides of the active layer; two distributed Bragg reflectors that sandwich the first resonance region and face each other, each of the distributed Bragg reflectors including periodically stacked low refractive index layers and high refractive index layers; and a current confinement structure that defines a current injection region for injecting a current into the active layer; wherein at least one of the distributed Bragg reflectors includes a second resonance region, wherein the second resonance region includes an opening therein, the opening being arranged such that it includes a center of the current injection region and extends toward an inner boundary of the current injection region, and wherein there is no resonance in the opening.
