Tune-out Wavelength Measurement and Gyroscope Using Dispersion Compensation in an Atom Interferometer
This Dissertation describes how I used a three nanograting Mach-Zehnder atom beam interferometer to precisely measure a wavelength of light, known as a tune-out wavelength, that causes zero energy shift for an atom. I also describe how such measurements can be remarkably sensitive to rotation …

Optical Enhancement in Periodic Plasmonic Gratings for SERS and Metal-Semiconductor-Metal Photodetectors (MSM-PDs) Applications
… In addition, the impact of the period of the nanograting, single and dual-width structures, is examined as well. Then, a comparison is conducted between these types to determine the optimum periods. The results show that dual-width structures can improve the incident light two times more than …

Phase and Polarization Modulations based on LCOS SLM
… state is required to encode information onto the nanograting structure created by laser pulses. In data writing beam generation, phase-only LCOS SLM can generate arbitrary data pattern by using diffractive holographic imaging. However, the polarization control of output image is still achieved by …

Enhanced Rainbow Trapping in Width-graded Chirped MIM Nano-gratings for High-sensitivity Multiwavelength Bio-molecular Detection
In this dissertation, we undertake theoretical and experimental investigations of plasmonic width-graded nano-gratings vis-à-vis a nanophotonic sensing platform amenable for integration within a Lab-on-a-Chip Point-of-Care system. Theoretically, we delineate the four principal surface plasmon …
