Modes in inhomogeneous slab waveguides
IEEE Journal of Quantum Electronics, 1974In this correspondence we have developed the perturbation approach for the calculation of propagation constants for some of the practical slab waveguides and have shown the applicability of the approach to systems of practical interest.

Scaling rules for slab waveguides with nonlinear substrate
Applied Optics, 1987A mode power measure is introduced to characterize optical slab waveguides with nonlinear substrate or cover. Together with the normalized film thickness and asymmetry coefficient, it allows for determining guiding properties in a way analogous to the description of Kogelnik and Ramaswamy for the linear waveguides and permits an easy interpretation and

Abstract We consider a planar waveguide in which there is a confined cholesteric liquid crystal whose helical axis is perpendicular to its plane boundaries. We write the electromagnetic equation for describing the dynamics of the propagating modes inside the guide and solve them numerically.

The origin of guided-wave behavior is presented for the case of slabs and for thin films of dielectric materials. The discussion examines the origin of the guided wave using a classical optics approach and that of Maxwell’s equations, as well as the matching of fields at the interfaces of dielectric layers.

Abstract Technological development in the telecommunications and related areas have made available a wide variety of optical structures such as thin silica rods, hollow cylinders, fiber bundles, and many planar geometries such as thin films or channels resting on flat substrates.

Class of resonator for slab waveguide lasers
Applied Optics, 2014We describe a class of laser resonator, incorporating a feedback collimator (FBC), that provides feedback that is mode-matched onto a higher-order lateral mode of a slab waveguide laser. In addition, this same resonator, in outcoupling, converts the stabilized higher-order lateral mode into an essentially laterally collimated output beam with a width ...
