Analysis and Design of Special-Type Optical Waveguides (IV)

In this research the full-vectorial finite
element method (FEM) based on linear
hybrid edge/nodal elements with triangular
shape and having perfectly matched layer
(PML) absorbing boundaries will be
generalized by employing curvilinear
elements for more accurately analyzing
waveguides with curved boundaries, such as
optical fibers and photonic crystal fibers.
The established numerical model can analyze
vector modes and leaky characteristics of
various photonic crystal holey fibers. We
have studied holey fibers and photonic band
gap fibers of different numbers of air-hole
rings. A two-dimensional beam propagation
method model based on the finite element
method and with perfectly matched layer
absorbing boundaries has also been
developed for investigating various
properties of slab waveguides including
ARROWs.
