Abstract:
Based on the Galerkin's method,
a numerical method is developed
to analysis the cutoff frequencies of guided modes
of optical waveguides with arbitrary refractive index profile.
Solutions are presented in the quasi-vector regime.
Optical waveguide structures with single core of arbitrary shape
are considered in this paper. The calculated results
are compared favorably with exact vector solution and
circular-harmonic expansion method.
