主权项 1. A vertical cavity surface emitting laser comprising: a substrate; a laminated body which is provided over the substrate, the laminated body including a first mirror layer which is provided over the substrate, an active layer which is provided over the first mirror layer, and a second mirror layer which is provided over the active layer; an insulation layer provided on the first mirror layer and surrounding the laminated body, wherein, in a plan view, the laminated body includes a first distortion imparting portion, a second distortion imparting portion, and a resonance portion which is provided between the first distortion imparting portion and the second distortion imparting portion and resonates light generated by the active layer, and an angle formed by a side surface of the first distortion imparting portion and an upper surface of the substrate, and an angle formed by a side surface of the second distortion imparting portion and the upper surface of the substrate are greater than an angle formed by a side surface of the resonance portion and the upper surface of the substrate.
