Abstract

Expressions are derived for the reflectivity and conversion coefficients of modes reflected by the end facet of a laser with waveguiding both in the transverse and the lateral directions. The modes are obtained by the effective-index method. The mathematical treatment takes into account the vectorial nature of the fields inside as well as outside the laser. It is assumed that Ex = 0, but all other field components do not vanish (TE-like modes). Expressions for the far-field pattern are also given, taking into account the reflectivity and mode conversion at the laser facet.
