Abstract
In this research, in addition to
generalizing the full-vectorial finitedifference
based optical waveguide mode
solver we established so that we can now
analyze waveguides involving anisotropic
materials with diagonal permittivity and/or
permeability tensor and waveguides with
leaky characteristics, we have quite
completely established another finitedifference
frequency-domain (FDFD)
method model based on Yee mesh. In the
topic of the finite-difference time-domain
(FDTD) method, we continue to employ the
established two-dimensional (2-D) numerical
models to simulate and study planar photonic
crystal waveguide devices and high-indexcontrast
high-density integrated-optic device
structures, and further more, we have
successfully established the 3-D model.
Based on pseudospectral methods, we have
also established a 2-D mode solver for
analyzing leaky slab waveguides and a
highly accurate 3-D solver for 3-D
waveguides.
