Johar, Umar Mohammed (1992) All optical reflectivity modulation utilizing surface plasmon resonance. Masters thesis, King Fahd University of Petroleum and Minerals.
The purpose of this thesis is to demonstrate an all optical reflectivity modulator that utilize surface plasmon resonance. The configuration of the structure is the well known Kretschmann configuration. It consists of a thin metallic layer deposited on the base of a high index prism. A region of saturable nonlinear medium exists under the metallic layer. A TM-polarized light (light to be modulated) is incident into the structure from the prism side and the modulating light is incidence into the structure from the bottom. It was assumed that only the modulating beam affects the nonlinear medium. Relationship between the itensity of the lower beam and the reflectivity was studied. In addition, the effect of changing the angle of incidence of the upper beam on the reflectivity was investigated. Furthermore, the effect of increasing the saturation level on the modulation was investigated. The applicability of the self-consistent approach for TM-polarized waves was also discussed.
