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
study the power transmission characteristics of different kinds of waveguides
for several materials and analyze their performance using the FDTD method.
SPP propagation characteristics through different optical nanostructures having
different geometries have been investigated to analyze the performance of the
materials. Waveguides with different kinds of bends have been investigated and
compared with each other to see the effects of these bends on the efficiency of
power transmission. All of the simulations have been done for a range of signal
wavelength extending beyond the visible light spectrum.
