Indoor free-space optical communication enhanced by dynamic optical beam control

Creator:: Trotter, Cade W.
Abstract:: This work expands the field of indoor free-space optical communication by introducing novel techniques in short range optical communication. The increasing need for high bandwidth communication necessitates the transition to optical frequencies with hundreds of terahertz worth of unregulated bandwidth. Optical communication offers an inherent security advantage over traditional communications...

Surface-Enhanced Infrared Absorption Gas Sensing Incorporating Advanced Plasmonic Nanostructures and Nano-Composite Materials

Creator:: Chong, Xinyuan
Abstract:: This dissertation focuses on extending the application scope of surface enhanced infrared absorption spectroscopy to gas sensing. The method we propose is incorporating plasmonic nanostructures with nano-composite material, metalorganic framework, which can selectively preconcentrate certain gas molecules into the nanopores. The preconcentrating property is first demonstrated by applying metal-organic framework...

Surface-Normal Modulation of Fano Resonances in Metallic Photonic Crystals for Free-Space Optical Interconnects

Creator:: Ren, Fanghui
Abstract:: This dissertation focuses on the development of ultra-compact optical devices for free-space modulation. We propose a surface-normal modulator using metallic photonic crystals for free-space optical interconnects. The active control of light intensity is achieved by engineering the Fano resonances in metallic photonic crystals. Both thermo-optic modulation and electro-optic modulation of...
