Abstract
In this research we have generalized the
full-vectorial finite-difference based optical
waveguide mode solver we established so
that we can now analyze waveguides
involving anisotropic materials with diagonal
permittivity and/or permeability tensor. We
have investigated efficient methods for
treating dielectric interfaces in the waveguide
to obtain more accurate numerical results. As
for the finite-difference time-domain method,
in this research we have established twodimensional
numerical models for both
transverse-electric and transverse-magnetic
waves. We have also investigated in detail
the relationship between numerical
convergence and the arrangement of the
computational grids. The models have been
successfully applied to the simulations of
photonic crystal waveguide bends and
splitters, micro-ring waveguide resonators,
high-index-contrast waveguide bends, and
various high-density integrated-optic device
structures.
