ABSTRACT:
Distributed Bragg reflector (DBR) with reduced DX centers. A DBR includes an AlAs region. The AlAs region includes essentially homogeneous AlAs. The DBR further includes a A1GaAs region. The AlGaAs region includes alternating thin layers of AlAs and GaAs. The alternating thin layers of AlAs and GaAs are arranged such the the AlGaAs region appears as a layer of A1GaAs with appropriate concentrations of Al and Ga.
