Semiconductor distributed Bragg reflector and optical communication systems and optical interconnection systems and surface-emitting laser module and surface-emitting laser array and surface-emitting semiconductor laser element

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor Bragg reflector capable of reducing resistance and light absorption loss without reducing a reflection factor.;SOLUTION: A p-type semiconductor distribution Bragg reflector I and a p-type semiconductor distribution Bragg reflector II which are successively laminated in the lamination direction are different in thicknesses at intermediate layers (linear composition inclination layer).;COPYRIGHT: (C)2004,JPO
