Vertical cavity surface emitting laser element, method of producing vertical cavity surface emitting laser element, and photoelectric conversion apparatus

Abstract

[Object] To provide a vertical cavity surface emitting laser element having excellent electric responsiveness and high productivity and reliability, a method of producing the vertical cavity surface emitting laser element, and a photoelectric conversion apparatus. [Solving Means] A vertical cavity surface emitting laser element according to the present technology includes: a semiconductor stacked body. The semiconductor stacked body is a semiconductor stacked body that includes a first mirror having a first conductive type, a second mirror that has a second conductive type and causes optical resonance together with the first mirror, an active layer provided between the first mirror and the second mirror, and a confinement layer that is provided between the first mirror and the second mirror and has a non-oxidized region and an oxidized region, the non-oxidized region being formed of a first material, the oxidized region being provided around the non-oxidized region and being formed of a second material obtained by oxidizing the first material, and has a mesa having an outer peripheral surface from which end surfaces of the active layer and the confinement layer are exposed and an ion implantation region that is a region into which ions have been implanted, is formed to reach a predetermined depth in the active layer and the confinement layer from the outer peripheral surface, and is separated from the non-oxidized region.
