Abstract
Optics and photonics are exciting, rapidly developing fields building their success
largely on use of more and more elaborate artificially made, nanostructured
materials. To further advance our understanding of light-matter interactions in
these complicated artificial media, numerical modeling is often indispensable.
This thesis presents the development of rigorous finite-difference method, a very
general tool to solve Maxwell’s equations in arbitrary geometries in three dimensions,
with an emphasis on the frequency-domain formulation. Enhanced
performance of the perfectly matched layers is obtained through free space
squeezing technique, and nonuniform orthogonal grids are built to greatly improve
the accuracy of simulations of highly heterogeneous nanostructures. Examples
of the use of the finite-difference frequency-domain method in this thesis
range from simulating localized modes in a three-dimensional photonic-crystal
membrane-based cavity, a quasi-one-dimensional nanobeam cavity and arrays
of side-coupled nanobeam cavities, to modeling light propagation through metal
films with single or periodically arranged multiple subwavelength slits.
