ABSTRACT

 

In this paper, we present a modeling analysis of Distributed Bragg Reflector (DBR) mirror comprises of alternating GaAs and AlGaAs semiconductor layers. Highly reflective mirror exceeding 99% has been obtained in this mirror, making the mirror system very promising for optoelectronics devices application. The optical properties derived from simulated reflectivity and absorption spectrums of the GaAs/AlGaAs DBR mirror are reported.
