HAWKINS - ARROWs

ARROW stands for Anti-Resonant Reflective Optical Waveguide. These structures are unique because they allow for the guiding of light in waveguides with air or liquid cores. The purpose of this project is the fabrication and study of ARROW structures and the construction of photonic devices built using ARROWs. Project sponsored by NIH, NSF, and DARPA.

Project relies on: Advanced Lithography Development, Metal and Dielectric Deposition, Chemical Etching of Core Materials, Research in Micro-fluidic Handling and Packaging, Scanning Electron Microscopy


HAWKINS – MICRO FILTERS

Project relies on: Advanced Lithography Development, Metal and Dielectric Deposition, Chemical Etching, RIE Etching, packaging

Microfilters are made on silicon substrates and consist of microfluidic channels in which very precise pores are etched. These pores would be used to remove a variety of bioparticles from a complex fluid mixture. One application would be the removal of bacteria and viruses from blood.


SCHULTZ - OPTICAL FIBER DEVICES

Fiber Grating Interrogator• Make short fiber Bragg grating

for the measurement of strain• Refine the high speed FBG

measurement

Electric field sensing• Slab coupled optical field sensing

(SCOS)• Create optical fiber based electric

field sensing elements• Refine detection electronics


BANGERTER – MAGNETIC RESONANCE IMAGING

Quantitative Sodium MRIThis project seeks to improve the measurement of sodium concentrations with MRI through pulse sequence innovations, better coils, and sophisticated post-processing techniques. Applications include quantitative assessment of cartilage health and characterization of tumors.

Improved MRI of Breast CancerIn this project, we are developing new sodium imaging techniques, improved accelerated proton imaging techniques, and phased-array coil designs for imaging of breast cancer tumors in vivo.

Diffusion Tensor MRI with Non-Linear High-Performance GradientsThis project seeks to improve diffusion tensor imaging sensitivity and SNR through the use of non-linear high-performance gradient inserts available at the University of Utah.

All projects rely on advanced signal/statistical processing models, noise analysis, image acquisition modeling, image processing, and familiarity with MRI scanning techniques.
