  • 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...

  • Design Techniques of High-Speed Silicon Photonics Transceiver

    Creator:
    Li, Hao
    Abstract:
    The rapid scaling of network bandwidth and data center throughput has motivated the wide adoption of high speed transceivers. Silicon photonics (Si-Photonic) is one of the most promising techniques to realize tightly integrated optical transceivers for next-generation high speed I O standards. This dissertation focuses on the design techniques of...

  • 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...

  • 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...

  • Design techniques for low-power electrical and optical serial link receivers

    Creator:
    Bai, Rui
    Abstract:
    As computation power continues to grow, the demand for data transfer bandwidth is also rising. This is reflected in the increasing data-rate of high-speed links. However, the increase in data-rate is sustainable only if the I/O energy efficiency improves as well. This dissertation explores several techniques to enable high-speed links...

  • A market oriented approach to energy conservation identifying disadvantaged families as target groups for energy assistance programs

    Creator:
    Marganus, Martin
    Abstract:
    Energy expenditures, perceived family well being, and energy conservation actions were analyzed by family composition and level of income. Data were from a three state subsample (Arizona, Colorado, and Oregon; N = 2,633) of a larger stratified random sample of households in the Western United States. Data were collected in...

  • Automated Monitoring of Construction Operations for Data-Driven Decision Making

    Creator:
    Rashid, Khandakar, M.
    Abstract:
    The continuous improvement of construction operations requires a systematic approach of monitoring and making appropriate control actions. However, the lack of real-time information hinders this workflow and eventually compromises timely and effective decision-making. Project managers spend a great deal of time and effort to solve problems emerging from lack of...

  • Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

    Creator:
    Sharp, Christopher J.
    Abstract:
    Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

  • Optimization of staged rankine energy conversion cycles for high efficiency

    Creator:
    Simmons, Larry Dean
    Abstract:
    Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...
