  • Hue constrained matrix optimization for preferred color reproduction

    Creator:
    Zhang, Heng, Liu, Huaping, and Quan, Shuxue
    Abstract:
    A method for preferred color reproduction with a psychophysical study based upon a real-life scene demonstrated application is presented. A color correction matrix optimization algorithm is first introduced which applies additional hue constraints on top of the CIE delta E magnitude error to emphasize the importance of hue in the...

  • Ring Amplifiers for Switched Capacitor Circuits

    Creator:
    Hershberg, Benjamin, Weaver, Skyler, Sobue, Kazuki, Takeuchi, Seiji, Hamashita, Koichi, and Moon, Un-Ku
    Abstract:
    In this paper the fundamental concept of ring amplification is introduced and explored. Ring amplifiers enable efficient amplification in scaled environments, and possess the benefits of efficient slew-based charging, rapid stabilization, compression-immunity (inherent rail-to-rail output swing), and performance that scales with process technology. A basic operational theory is established, and...

  • 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...

  • Multi-Modal Biosensing with Diatom Photonic Crystal Biosilica

    Creator:
    Squire, Kenneth J.
    Abstract:
    The need to detect trace amounts of target molecules is great, particularly when it comes to biosensing. With the early detection of a disease, the odds of the successful treatment of an individual increases significantly. To enhance the capability of biomolecular detection, we have created an optical biosensor capable of...

  • 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...

  • 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...

  • Silicon nanomembrane based photonic crystal waveguide array for wavelength-tunable true-time-delay lines

    Creator:
    Lin, Che-Yun, Subbaraman, Harish, Hosseini, Amir, Wang, Alan X., Zhu, Liang, and Chen, Ray T.
    Abstract:
    We demonstrate a four-channel on-chip true-time-delay module based on a photonic crystal waveguide array. Using the photonic crystal taper to minimize the coupling loss, the delay lines with 1-3 mm long photonic crystal waveguides can operate up to a group index n(g) similar to ~23 without significant loss. The large...

  • 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...

  • Photonic Sintering of Nanoparticle Inks : Experimental Characterization, Computational Modeling and System Design for Additive Manufacturing

    Creator:
    MacNeill, William D.
    Abstract:
    Photonic sintering of nanoparticles is a relatively new process for sintering of nanoparticles, deposited on a substrate, into functional solid structures. The working principle of this process is the incidence of large-area broad-spectrum light onto deposited nanoparticles, which results in heat generation in the nanoparticles and their subsequent densification. Key...
