Manipulation Of Light In Plasmonic Nano-Structures, Rehab Kotb Abd-Allah

Theses and Dissertations

Manipulating light at nano-scale is usually shadowed by the diffraction limit. Recently, plasmonics have emerged as a new technology that enables confining light at nano-scale. Using plasmonic structures, photonic devices can be shrunk from the micro-scale to the nano-scale. In this thesis, a novel structure to a plasmonic nano-filter is introduced and analyzed. The proposed nano-resonator has low loss, compact size and good sensing characteristics. A closed form model to the filter behavior is developed. The model is extracted from the waveguide physical parameters and provides a physical insight into the structure of the filter. An analytical model to the …
