| Summary: | This paper provides a numerical simulation for determining the complex propagation
constants of integrated optics waveguide. The waveguide under consideration may
consist of any number of layers with complex indices due to gain and loss. A general-
purpose mode solver MAPLE program has been developed to implement the transfer
matrix method, and then it applied to solving the multilayer waveguide dispersion
equation in complex plane. Additionally, our program can be used to determine the
electromagnetic mode structure including modal power, spatial distribution, mode size
parameters, and the position of the modal peak power. Therefore, all necessary
parameters for a wide range of laser devices can be calculated. |
