“…The zero-order guided mode has the highest refractive index (n TE 0 e = 1.729); the guided mode of the highest order has an effective index near to the refractive index of the substrate (n TE 8 e = 1.451). In the case of the LMM the existence of leaky modes [10] in addition to the guided modes is considered. indices of these modes, determined by solving the dispersion equation of this leaky waveguide, are located between 1 and n s because they undergo a total reflection at the air side and a partial reflection at the substrate side.…”

Two novel methods to control the polarization of laser radiation are presented. The discrimination between different polarization distributions is performed with a corrugation grating in the top high-index layer of a multilayer mirror, which couples the undesired polarization into a lossy waveguide mode of the multilayer. The generation of radially polarized radiation in a laser resonator is presented as a practical verification of the principle.
