Paper Abstract

According to Analytic Transfer Matrix (ATM) Method, it is possible to precisely determine the modal characteristics of a planar optical waveguide with arbitrary index profiles. In this paper, we present an Inversed Analytic Transfer Matrix (IATM) method to predict the refractive index profiles from measurement of mode indices, which has been proved to be valid even when solving some problems that inversed WKB method would find difficult.
