Abstract
In Optical Integrated Circuits (OIC) and optical device design (passive and active), the index of refraction profile is a coordinate-dependent parameter. Specially in slab waveguides, which is a basic element in optical engineering, the guided modes and their behaviors with respect to waveguide parameters can be extracted from the exact solution of the Helmholtz equation. In general case, the numerical approach is applied for the determination of the electric and magnetic fields. In this paper a suitable algorithm, using the PT-symmetric quantum-mechanical approach, has been given for light transmission through one-dimensional inhomogeneous media (PT-symmetric index of refraction).
