Abstract
An analytic expression for the main mode reflectivity of a multicoated laser facet at normal incidence is derived using the free space radiation mode technique. This uses exact guided modes, and accurately models the radiation modes near the facet. The results compare favorably with exact TE and TM benchmarks while retaining the simplicity and speed of the Fresnel approximations.<>
