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...

Silicon Photonic Devices With Tunable Temperature Dependence

Researchers at the University of Arizona have developed an athermal multichannel optical add-drop multiplexer (OADM) which is based on silicon microring resonators. Using a means of controlling the thermo-optic coefficient of certain materials, the researchers have reduced the temperature dependent wavelength shifts to achieve athermal condition for...

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...

SHG Imaging Technique for Assessing Hybrid EO Polymer/Silicon Photonic Integrated Circuits

Scientists at the University of Arizona have developed a system for assessing the efficiency of the electro-optic (EO) polymer poling process by using multi-photon imaging in the second harmonic generation mode (SHG), permitting imaging and assessment of waveguide devices, including poled polymer devices, prior to, during, and after fabrication. This...
