    Parameter Extraction of Optical Materials and Investigation of Surface Plasmon Polariton (SPP) Propagation in Different Optical Nanostructures
    (Department of Electrical and Electronic Engineering, Islamic University of Technology (IUT), Board Bazar, Gazipur-1704, Bangladesh, 2013-11-15) Saber, Md. Ghulam; Noor, Asif Al; Al-Amin, Md. Thesun
    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
