Document Type and Number:
Japanese Patent JP7434849
Kind Code:
B2
Abstract:
A surface emitting laser includes a first reflecting mirror; a second reflecting mirror; an active region between the first reflecting mirror and the second reflecting mirror. The first reflecting mirror and the second reflecting mirror each include a plurality of low refractive-index layers having a first refractive index; and a plurality of high refractive-index layers having a second refractive index higher than the first refractive index. The plurality of low refractive-index layers and the plurality of high refractive-index layers are alternated one after another. The plurality of high refractive-index layers of the first reflecting mirror includes a first layer; and a second layer having a higher thermal diffusion property in an in-plane direction than the first layer.
