Abstract
A surface emitting laser element includes a lower DBR formed on a substrate; an active layer formed above the lower DBR; an upper DBR formed on the active layer. The upper DBR includes a dielectric multilayer that is formed as a result of dielectrics having different refractive indexes being alternately laminated and formed, a light shielding part is formed above the upper DBR, and the light shielding part has an opening at a central area for emitting light.
