Optical Printed Circuit Board with Polymer Array Switch

Researchers at the University of Arizona have developed a flexible polymer waveguide array structure that serves as a stitch or jumper on an optical printed circuit board (OPCB). The flexible polymer waveguide array structure can be attached to the OPCB so that it can provide a chip-to-OPCB optical connection. Using an array of small polymer waveguides...

High-Throughput Manufacturing for PIC Polymer Waveguide Connection Fabrics

This invention is a low-cost high-throughput method of connecting silicon photonic chips to one another. The method is active and robust, taking into account the tolerances and variations of the PIC configurations. It is also rapid, accurate, immune to large dimensional variation, and amenable to rework. Background: Photonic integrated circuits (PICs)...

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...

Relaxed Tolerance Adiabatic Coupler for Optical Interconnects

Researchers at the University of Arizona have designed an architecture for photonic integrated circuits (PICs) using a waveguide design that reduces the size of the interconnections and overcomes the mode size mismatch. The design also relaxes alignment tolerances and lower polarization dependence to allow for very fast manufacturing of the PIC interconnections. Background:...
