Abstract

A vertical cavity light emitting device (10) includes: a first multilayer film reflector (13); a semiconductor structure layer that is formed on the first multilayer film reflector and includes a first conductivity type semiconductor layer (15) , an active layer (17), and a second conductivity type semiconductor layer (19); an insulating current confinement layer (21) formed on the second conductivity type semiconductor layer; a through opening formed in the current confinement layer; a transparent electrode (23) for covering the through opening and the current confinement layer, the transparent electrode being in contact with the second conductivity type semiconductor layer through the through opening; a second multilayer film reflector (25) formed on the transparent electrode; and a mixed composition layer (24) formed to be in contact with an edge of the through opening and in which the current confinement layer and the transparent electrode are mixed.
