  • Examining China's Cross-strait Economic Statecraft in the Mid-2000s

    Creator:
    Chi, Erik
    Abstract:
    In 2005, Beijing acted to court the farmers of Taiwan through a series of unilateral agricultural tariff reductions. This move was deliberately formulated to weaken the incumbent Democratic Progressive Party (DPP) by targeting the party's strong rural base. This paper seeks to investigate the effectiveness of China's use of interest...

  • 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...

  • Optical Sensors using Biological Photonic Crystals

    Creator:
    Squire, Kenneth James
    Abstract:
    This dissertation focuses on the application of diatom frustules, the biosilica shell of an algae possessing physical and photonic properties capable of enhancing optical signals, for the enhancement of optical sensing. In this work, we incorporate diatom frustules into biosensors for signal enhancement and improved target molecule detection. The potential...

  • 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...

  • Plasmonic Nano-Antenna and Modulator for On-Chip Optical Interconnects

    Creator:
    Gao, Qian
    Abstract:
    With the rapid growth of worldwide internet traffic in data centers and clouds, silicon photonics has been utilized to provide enormous data bandwidth and outstanding energy efficiency over electronics. Computing servers and storage servers that are connected by communication links are relying more on optical rather than electrical means mainly...

  • 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...

  • Ultra-energy-efficient Silicon Photonic Modulators Driven by Transparent Conductive Oxides

    Creator:
    Li, Erwen
    Abstract:
    Silicon photonics has become the most promising platform for future large-scale optical interconnect and optical computing systems due to its inherent CMOS compatibility, which brings exclusive advantages in bandwidth density, energy efficiency, and cost effectiveness. Parallel optical interconnects based on photonic integrated circuits (PICs) have the capacity to meet the...

  • Multi-channel Stochastic Resource Allocation and Dynamic Access Scheduling

    Creator:
    Wang, Qiwei
    Abstract:
    Modern communication systems often have the ability to transmit signals on multiple communication mediums (e.g., RF, visible light) or interfaces (e.g., MAC layer protocols) at the same time. While each channel has different characteristics, a centralized controller with channel condition information will be able to schedule the resource allocated to...

  • Application of Coupled Oscillator Model to Terahertz and Optical Control of Plasmon Induced Opacity in Coupled Metamaterials

    Creator:
    Sprague, Milo X.
    Abstract:
    Terahertz (THz) frequencies of the electromagnetic spectrum have been underutilized when compared to neighboring microwave and infrared frequencies, largely due to the difficulties controlling and detecting these fields. In a step toward gaining control over THz frequencies, my advisor Dr. Yun-Shik Lee’s group experimentally demonstrated optical-pulse THz-control over a plasmonic...

  • Development of thermosensitive injectable hydrogel and transdermal controlled release formulations for Tacrolimus

    Creator:
    Nguyen, Duc X.
    Abstract:
    TAC is the most commonly used medication in post transplantation maintenance immunosuppression therapy. TAC lipophilicity and its erratic oral absorption especially in the presence of food intake result in great intra- and interpatient pharmacokinetic variations. Complicated dosing and frequent required therapeutic monitoring is thought to be the main cause of...
