Quasi-vertical tapers for polymer-waveguide-based interboard optical interconnects

Fan-out routing and optical splitting techniques for compact optical interconnects using single-mode polymer waveguides

Polymer waveguide (WG) S-bends are necessary for fan-out routing techniques and optical splitting in high-density optical interconnects. Designing and manufacturing of optimal S-bends are critical for minimizing optical link loss while maintaining overall size and layout constraints. Complete structural loss analysis is demonstrated theoretically and shown experimentally utilizing both radial a...

Polymer optical waveguide based bi-directional optical bus architecture for high speed optical backplane

With the technology trend of using optical interconnects as an alternative to traditional copper interconnects, basic elements such as waveguides and waveguide bus structure are studied worldwide. A novel 3-node bi-directional 50μm optical waveguide bus architecture with embedded mirrors is proposed and fabricated on flexible substrate. The fabrication is achieved by lithography-free molding.

Design and Fabrication of Optical Polymer Waveguide Devices for Optical Interconnects and Integrated Optical Coherence Tomography

Low-cost board-to-board optical interconnects using molded polymer waveguide with 45 degree mirrors and inkjet-printed micro-lenses as proximity vertical coupler.

We demonstrate intra- and inter-board level optical interconnects using polymer waveguides and waveguide couplers consisting of both 45 degree total internal reflection (TIR) mirrors and inkjet-printed micro-lenses. Surface normal couplers consisting of 50 µm × 50 µm waveguides with embedded 45 degree mirrors are fabricated using a nickel mold imprint. Micro-lenses, 70 µm in diameter, are inkje...
