THE FREE-SPACE RADIATION MODE METHOD FOR THE ANALYSIS OF COATED ANGLED FACETS AND COMPARISON WITH A FDTD METHOD

The free-space radiation mode method is extended to provide accurate semianalytical formulas for the reflectivity of a polarized optical waveguide mode incident on a coated laser facet at an arbitrary angle. Solutions may be obtained easily and with minimum computational effort. Results obtained are compared with those from a finite-difference-time-domain method. © 1997 John Wiley & Sons, Inc.
