Abstract:
1. A method for producing an optoelectronic component with three-dimension quantum well structure, comprising: A. growing a transition layer on a buffer layer disposed on a substrate; B. applying a first mask layer to said transition layer, wherein said first mask layer has at least a first opening exposing a part of said transition layer; C. etching said transition layer from said first opening to form a trench; D. removing said first mask layer; E. applying a second mask layer to said transition layer, wherein said second mask layer has at least a second opening exposing a different part of said transition layer adjacent to said trench; F. growing a protrusion over said second opening; G. removing said second mask layer to expose said trench and said protrusion; H. applying a third mask layer to said transition layer and said protrusion, wherein said third mask layer has at least a third opening exposing a part of said protrusion; I. growing another protrusion over said third opening; J. removing said third mask layer to expose said trench and said protrusions; and K. forming at least a pair of quantum well structures on said trench and said protrusion.
