High Verdet Constant Polymer Magnetic Nanoparticle Materials for Magneto-Optic Devices
University of Arizona researchers have developed high Verdet constant thin films using polymer-nanoparticle composite material. The invention provides for uniform distribution of nanoparticles in a polymer matrix. The resulting inexpensive material possesses very high Verdet constants, exceeding one million / T-m. This material enables replacement of...

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...
