Abstract: | In optical Integrated circuits (OIC) and optical device design (passive and active), the index of refraction profile is a coordinate dependent parameter. Specifically in slab waveguides which is a basic element in optical engineering, the guided modes and its behavior with respect to waveguide parameters can be extracted from the exact solution of the Helmholtz equation. In the general case, the numerical approach is applied for 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).Received: 6 October 2003, Published online: 23 December 2003PACS: 03.65.-w Quantum mechanics - 03.50.De Classical electromagnetism, Maxwell equations - 42.82.Et Waveguides, couplers, and arrays |
