Standoff Barcode Reader that uses an Entangled Transmitter (Light-Squeeze-o-Matic-Barcode-Readatron R)
This technology is a barcode reader that utilizes an entangled transmitter that allows better performance especially when the detected light has undergone loss and noise.
Background:
When the observed light has been subjected to loss and noise on its way to the receiver, entanglement-assistance improves efficiency in discrimination and communication...

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...
