Abstract

Typical Bragg mirrors have an air–dielectric interface that can have a reflectivity spectrum different from that calculated by simple coupled-wave theory because of Fresnel reflection at their surface. This additional reflection can add constructively or destructively, depending on the sequence of the Bragg layers. We show a method of analysis for calculating reflectivity of Bragg mirrors in the presence of additional reflections.
