摘要:
A stack of distributed Bragg reflectors is disposed on the surface of a semiconductor substrate. The stack includes a plurality of alternating layers of material having alternating refractive indexes with the stack having a first dopant type. A first cladding region is disposed on the stack with an active area disposed on the first cladding region. The active area includes at least two barrier layers and a quantum well layer. A second cladding region is disposed on the active area with a stack of distributed Bragg reflectors disposed on the cladding region. A contact region is disposed on the second stack of distributed Bragg reflectors. The contact region includes a magnesium doped gallium phosphide material.
