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...

High Refractive Optical Polymers from Vinylic Sulfide Monomers Amenable to Photoprocessing
This invention is a new class of hybrid inorganic-organic polymer chemistry for synthesizing high refractive index optical polymers. Monomers for these materials comprise vinylic groups linked to a protecting group capable of being cleaved upon application of an external stimulus. The refractive index of the polymer may be changed during the process...
