POLYMER-BASED INTERCONNECTION BETWEEN SILICON PHOTONICS DEVICES AND OPTICAL FIBERS

摘要

An apparatus includes a Silicon Photonics (SiP) device and a ferrule. The SiP includes multiple optical waveguides. The ferrule includes multiple optical fibers for exchanging optical signals with the respective optical waveguides of the SiP device. In some embodiments, an array of micro-lenses is configured to couple the optical signals between the optical waveguides of the SiP device and the respective optical fibers of the ferrule. In some embodiments, a polymer layer is placed between the SiP device and the ferrule, and includes multiple polymer-based Spot-Size Converters (SSCs) that are configured to couple the optical signals between the optical waveguides of the SiP device and the respective optical fibers of the ferrule.
