Abstract:
The ability of Surface-Plasmon-Polaritons (SPPs) to overcome the diffraction limit
has made it a field of great research interest. It is being predicted that next generation
microchips will be produced using plasmonics-electronics hybrid technology.
This will solve the RC-delay issue of current electronic microchips and scaling
issue of conventional integrated photonic devices. However, there are some shortcomings
of SPP which are higher losses in the metallic layer and less propagation
distance. Using current technology, propagation distance of SPP cannot exceed
the benchmark of micrometers. The objective of this thesis is to extract the modeling
parameters for several materials and analyze their performance using the
FDTD method. The modeling parameters have been extracted using an optimization
algorithm. The parameters were then used to define different materials in
the simulation model. SPP propagation characteristics through different optical
nanostructures having different geometries have been investigated to analyze the
performance of the materials. Finally, simple nanoplasmonic coupling structures
using gallium lanthanum sulfide and cuprous oxide have been proposed and investigated
that provide appreciable performance
