Patent ID: 6979582

Claim:
A method for producing a vertical-cavity surface emitting laser diode, comprising steps of: a) sequentially epitaxying an n-type cladding layer, an active layer with quantum well structure and a p-type cladding layer on a substrate; b) partially etching said p-type cladding layer, said active layer and an upper portion of said n-type cladding layer to expose a part of said n-type cladding layer; c) oxidizing lateral surface of said p-type cladding layer by wet oxidation to form an insulating area; d) disposing an annular p-type ohmic contact electrode on said p-type cladding layer close to said insulating area, and disposing and an n-type ohmic contact electrode on said exposed n-type cladding layer; e) depositing an upper DBR pair of dielectric material on said p-type cladding layer at least within said p-type ohmic contact electrode; f) bonding a glass substrate upon said upper DBR pair; g) removing said substrate provided in step a); h) depositing a bottom DBR pair of dielectric material beneath said n-type cladding layer; i) disposing a metal conductive layer beneath said bottom DBR pair; j) plating a permanent substrate beneath said metal conductive layer; and k) removing said glass substrate.
