Abstract:
Galerkin’s method is employed to analyze the quasi-vector
wave equation for optical waveguides with arbitrary refractive index
profile in a mapped infinite domains. Results are presented for a range of
waveguide structures which include rectangular core, circular core, rib, and
multiple quantum well. Solutions are compared favorably with exact vector
solution and numerical results using Fourier operator transform method
and beam propagation method.
