Abstract:
A light emitting diode with two AlGaAs and AlGaInp Bragg reflector layers comprising:an ohmic n-electrode on a rear surface of a GaAs substrate;a first, lower distributed AlGaAs Bragg reflector layer grown on the substrate;a first, lower n-AlGaInP cladding layer grown on the first Bragg reflector layer;a second, upper distributed AlGaInP Bragg reflector layer grown on the first cladding layer;an active layer grown on the second Bragg reflector layer;a second, upper p-AlGaInP cladding layer grown on the active layer;a GaInP window layer grown on the upper cladding layer; andan ohmic p-electrode on the window layer.
