Title:
VERTICAL RESONATOR-TYPE LIGHT EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/002198
Kind Code:
A1
Abstract:
A vertical resonator-type light emitting element which comprises: a substrate (11); a first multilayer film reflection mirror (12) that is formed on the substrate; a first semiconductor layer (13N) that is formed on the first multilayer film reflection mirror and has a first conductivity type; a light emitting layer (13A) that is formed on the first semiconductor layer; a second semiconductor layer (13P) that is formed on the light emitting layer and has a second conductivity type which is opposite to the first conductivity type, while having a projection (13PB) on the upper surface; an insulating layer (14) that covers the upper surface of the second semiconductor layer, while having an opening through which the second semiconductor layer on the upper surface of the projection is exposed, said projection being terminated on the upper surface; a translucent electrode layer (15) that is formed on the insulating layer so as to cover the upper surface of the second semiconductor layer, said upper surface being exposed through the opening of the insulating layer; and a second multilayer film reflection mirror (16) that is formed on the translucent electrode layer and constitutes a resonator together with the first multilayer film reflection mirror.
