SURFACE-EMITTING LASER, ELECTRONIC APPARATUS, AND METHOD FOR MANUFACTURING SURFACE-EMITTING LASER

Document Type and Number:

WIPO Patent Application WO/2022/158301

Kind Code:

A1

Abstract:

Provided is a surface-emitting laser capable of preventing deterioration of luminous efficiency.　Provided is a surface-emitting laser comprising: first and second multilayer film reflective mirrors; a plurality of active layers laminated together between the first and second multilayer film reflective mirrors; a tunnel junction disposed between two active layers, from among the plurality of active layers, that are adjacent to each other in the lamination direction; and an oxidation constriction layer disposed between the tunnel junction and one active layer of the two adjacent active layers. This feature enables provision of a surface-emitting laser capable of preventing deterioration of luminous efficiency.
