Abstract:
1. A surface emitting laser comprising: a first mirror; a second mirror; an active layer formed between the first mirror and the second mirror; and a third mirror disposed between the first mirror and the active layer, wherein a first cavity is constituted by the first mirror and the second mirror, and a second cavity is constituted by the first mirror and the third mirror, wherein the first mirror, the second mirror, and the third mirror are multilayer mirrors having high refractive index layers and low refractive index layers that are alternately arranged, wherein, when the layer closest to the active layer in the second mirror is a high refractive index layer, the layer closest to the active layer in the third mirror is a low refractive index layer, and wherein, when the layer closest to the active layer in the second mirror is a low refractive index layer, the layer closest to the active layer in the third mirror is a high refractive index layer.
