<p> As the fundamental basic building blocks of photonic circuits, optical waveguide
structures play important roles in modem telecommunication and sensing systems.
Various structures ranging from the dielectric waveguide utilizing the total internal
reflection (TIR) to the more advanced structures based on the surface plasmon polaritions
(SPPs) are widely investigated and studied in industrial and research areas. With the fast
development of fabrication technologies, more and more complicated structures are
predicated to emerge as the requirement of highly integrated photonic circuits. Modeling
and simulation methods, as efficient as well as excellent cost performance tools
comparing to costly facilities and time-consuming fabrication procedures, are demanded
to explore and design the devices and circuits before their finalization. </p> <P> This thesis reports a series of techniques to model two dimensional waveguide
structures, including the conventional planar and surface plasmon polariton waveguides.
This thesis contains both the methods and their applications to model and investigate the
mode and propagation characteristics including the guided waves and the radiative waves.
The methods include mode solvers based on fmite difference method (FDM) and
complex mode matching method (CMMM), furnished with perfect matching layer (PML)
for both guided and radiation modes. Based on the developed techniques, solutions of
design of Bragg gratings with deep corrugations are presented; also various surface
plasmon polariton (SPPS) grating structures are investigated. </p> / Thesis / Master of Applied Science (MASc)
