Patent ID: 7724799

Claim:
A Vertical-Cavity Surface-Emitting Laser diode (VCSEL) comprising; a substrate, a first distributed Bragg reflector of a first conductivity type, formed on the substrate and comprising at least one semiconductor layer to be oxidized, an active region having a column shaped structure on the first distributed Bragg reflector, and a second distributed Bragg reflector of a second conductivity type, at least one hole being formed in the first distributed Bragg reflector outside of a column shaped structure of the second distributed Bragg reflector, the hole being from a surface of the first distributed Bragg reflector and reaching the at least one semiconductor layer to be oxidized, and an oxidized region formed in the semiconductor layer to be oxidized, the oxidized region being selectively oxidized from a side surface of the at least one hole, and a first current path and a second current path being formed in the first distributed Bragg reflector, the first current paths being formed by a conductive region surrounded by the oxidized region, and the second current path being formed by a conductive region not surrounded by the oxidized region.
