Abstract:
An optoelectronic device that includes a germanium containing buffer layer atop a silicon containing substrate, and a first distributed Bragg reflector stack of III-V semiconductor material layers on the buffer layer. The optoelectronic device further includes an active layer of III-V semiconductor material present on the first distributed Bragg reflector stack, wherein a difference in lattice dimension between the active layer and the first distributed brag reflector stack induces a strain in the active layer. A second distributed Bragg reflector stack of III-V semiconductor material layers having a may be present on the active layer.
