Abstract
In this work the proven free space radiation mode (FSRM) method is extended to determine the polarization dependent reflectivity of a guided mode in a 2D waveguide incident at an arbitrary angle onto a facet. The FSRM method is an attractive semi-analytical method which is fast, simple and accurate and has previously been successful in cross sectional analyses, propagation and 1D facet problems. The method is applicable to a wide variety of practical buried structures with small lateral index variations. Novel 2D results for the reflectivity of polarized and vector modes at a n angled facet are provided.
