Abstract

The effect of doping and structural nonuniformities in AlxGa1-xAs distributed Bragg reflectors is investigated theoretically The reflectors appear to be quite resistant to random fluctuations in thickness. Depending on the structure of the mirror, doping and small variations in composition may change the reflectivity spectrum essentially, indicating the importance of including doping in the mirror design. Only p-type doping is analyzed. The different role of variations in the thickness or refractive index is studied analytically.
