Compound Dichroic Polarizer
Researchers at the University of Arizona have designed a device and method for converting states of polarization (SOPs) of light into separate colors. In essence, the device can code SOPs into easily distinguishable colors and color changes that are visible to the human eye, regardless of the wavelength of light illuminating the objects.

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...

A Broadband Apparatus for Generating and Sampling Polarization States
Researchers at the University of Arizona have developed thin-film polarization devices that generate and/or sample light-polarization states over a broad band (wide wavelength range) and over wide angles. The polarizers incorporate and exploit multiple polarization layer groups and can be integrated into a microarray and incorporated into a light source...

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...
