SmartPrint Polymer Material and Design for the Connection of Separate Optical Chips
This technology is a further development of interconnect polymer waveguides for photonics packaging and integration. Here, a flexible optical substrate is attached and aligned to individual photonic chip components to form an optical waveguide. The waveguide comprises a refractive index contrast (RIC) polymer directly patterned using a photolithography...

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...
