Optical filtering properties of inhomogeneous isotropic slab waveguides

摘要

Inhomogeneous optical slab or; channel wave-guides are basic alternative for realization of the passive and active de-vices and systems in the full-optical engineering domain. Usually, the exact treatment for obtaining the reflected and transmitted light is very hard and the numerical methods are used. In this paper, we will investigate the optical filtering properties of the exactly solvable large set of the inhomogeneous index of refraction profiles. We show that tuning of the inhomogeneous media length easily can control; the bandwidth of our proposed filter.
