Method of Rapid Nanophotonic Design and a Nanophotonic Waveguide to Fiber Coupler
Researchers at the University of Arizona have developed a rapid design approach for designing nanophotonic devices. The invention is a novel implementation of an iterative optimal approach related to the known coupled dipole modeling approach. The novel implementation is several orders of magnitude faster than finite difference time domain approaches.

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...
