Polymeric waveguides with embedded micro-mirrors formed by Metallic Hard Mold.

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...

Photolithography-free polymer optical waveguide arrays for optical backplane bus.

In this paper, an innovative 3-to-3 bi-directional optical bus architecture based on multimode polymer waveguides with embedded 45° micro-mirrors was successfully demonstrated. With a lithography-free imprinting process by high quality electroplated metallic mold, the device can be precisely replicated with a low fabrication cost. Superior to any point-to-point optical waveguide, the implemente...

Embedded Micro-Mirrors for Compact Routing of Multimode Polymer Waveguides

3D micro-optic circuits in holographic photopolymers

Three-dimensional direct-write lithography into diffusion-mediated photopolymers developed for holography is shown to create 10 micron single-mode waveguides. We demonstrate low-loss waveguides, 90 degree bends off of encapsulated mirrors and fabrication of waveguides to embedded fibers. ©2007 Optical Society of America OCIS codes: (160.5470) Polymers, (160.2900) Holographic recording materials...

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.
