Abstract:
A vertical cavity surface emitting laser includes: a substrate; a first mirror layer; an active layer; a second mirror layer; a first electrode which is electrically connected to the first mirror layer; a second electrode which is electrically connected to the second mirror layer; and a pad which is electrically connected to the second electrode, in which the first mirror layer, the active layer, and the second mirror layer configure a laminated body, the laminated body includes a resonance portion, an insulation layer is provided on a side surface of the laminated body, in a plan view, the insulation layer has a shape line-symmetrical with respect to a virtual straight line passing through a center of the resonance portion, the pad is provided over the insulation layer, and in the plan view, the pad is only provided on one side of the virtual straight line.
