Analysis of semiconductor microcavity exciton-polaritons with coupled harmonic oscillators

Creator:: Sakuragi, Mai
Abstract:: Terahertz (THz) time-domain spectroscopy provides insight into electron dynamics in semiconductor heterostructures. High-field THz spectroscopy probes the excitonic nonlinear response of GaAs quantum well (QW) systems and enables the measurement of its coherent dynamics in the time-domain. Consequently, THz spectroscopy allows one to explore the fundamental properties of many-body interactions...

Laboratory studies of growth conditions of Vibrio parahaemolyticus in Pacific oyster (Crassostrea gigas) with international considerations to shellfish-associated illnesses in South Korea

Creator:: Lee, Jeehye
Abstract:: Vibrio parahaemolyticus, a naturally occurring halophilic pathogen, is seasonally abundant in marine and estuarine environments. It is also the leading cause of gastroenteritis in humans world-wide. Numerous outbreak incidences associated with the pathogenic Vibrio parahaemolyticus contaminations in oyster products have raised public-health concerns as well as economic challenges to the...

Quantifying dissipative beach and vegetated dune morphology with multiple aerial photography systems

Creator:: Conlin, Matthew P.
Abstract:: Sand dunes provide coastal communities critical protection from flooding and erosion, as well as a habitat for a range of species- some threatened or endangered. As such, it is of importance to develop a quantitative understanding of the processes through which these systems evolve at a variety of temporal and...

Host plant dependent disease progression of the microsporidian parasite Nosema tyriae on Cinnabar moth larvae

Creator:: Berns, Kathryn, Buergi, Linda, and McEvoy, Peter
Abstract:: Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...

Non-destructive methods to determine microsporidian infection levels in cinnabar moth larva

Creator:: Woolsey, Kelsey, Büergi, Linda, and McEvoy, Peter
Abstract:: The Cinnabar moth, Tyria jacobaeae, has been introduced to North America in an effort to control the invasive plant Jacobaea vulgaris. The Cinnabar moth is the main host of Nosema tyriae. When infection levels are high, N. tyriae can shorten the lifespan and affect reproduction of the Cinnabar moths. The...

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...

High Field Terahertz Spectroscopy of Optically Excited Gallium Arsenide

Creator:: Compeau, James
Abstract:: High field time-domain terahertz spectroscopy (TDS) is used to determine the time dependent transmission and the time-delay and optical-power dependent conductivity of a wafer of gallium arsenide (GaAs). Gallium arsenide is a direct band-gap semiconductor and has potential as a computer processor component. Analysis of the transmission of terahertz (THz)...

Terahertz field enhancement in nanoantennas on gallium arsenide

Creator:: Brequigny, Victor
Abstract:: Terahertz (THz) spectroscopy is a great tool not only to study fundamental physical processes such as many-body Coulomb interaction but also to develop ultrafast electronic devices. More specifically, intense THz fields interacting with semiconductors have exhibited strong nonlinear effect involving extreme carrier dynamics. In this experiment, intense THz radiation was...

Plasmon Induced Transparency in Terahertz Metamaterials

Creator:: Meyers, Joseph
Abstract:: Plasmon induced transparency (PIT) describes a spectral response of coupled plasmonic resonators in that coupling between bright and dark modes leads to a destructive interference resulting in a narrow transparency window. This process has many applications in material characterization and advanced optical devices such as slow light devices or ultrafast...
