Mode Scrambler for Increasing Numerical Aperture
This project is one of the three improvements to a falloposcope under development described in UA19-249. This falloposcope was designed with optical elements selected for detection of early stage ovarian cancer in fallopian tube epithelium. The mode scrambler improvement in this project acts to widen and brighten the illumination profile to better serve...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

3D Printed Lens for Imaging in Falloposcope
This project proposes three improvements to a falloposcope under development. This falloposcope was designed with optical elements selected for detection of early stage ovarian cancer in fallopian tube epithelium. The data collected by the falloposcope is grounded in a growing body of medical research. Falloposcopes were used in the 1990s to treat...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
