ABSTRACT:
A structure and method for use in optical communication systems is provided in which a metal is diffused in a heterojunction region beneath a metal contact of a AlGaAs light emitting diode. This structure and method significantly reduces the contacting shadowing problem due to current crowding beneath the contact thus increasing the light output from the device.
