Abstract:
A vertical cavity surface emitting laser includes: a substrate; a first mirror layer; an active layer; a second mirror layer; a current constriction layer; a first area connected to the first mirror layer and including a plurality of oxide layers; and a second area connected to the second mirror layer and including a plurality of oxide layers. The first mirror layer, the active layer, the second mirror layer, the current constriction layer, the first area, and the second area configure a laminated body. The laminated body includes a first portion, a second portion, and a third portion between the first portion and the second portion. When a width of the oxide area is W1 and a width of an upper surface of the first portion is W2, W2/W1≦3.3.
