High-speed Light Peak optical link for high energy applications

Abstract Optical links provide high speed data transmission with low mass fibers favorable for applications in high energy experiments. We report investigation of a compact Light Peak optical engine designed for data transmission at 4.8 Gbps. The module is assembled with bare die VCSEL, PIN diodes and a control IC aligned within a prism receptacle for light coupling to fiber ferrule. Radiation damage in the receptacle was examined with 60 Co gamma ray. Radiation induced single event effects in the optical engine were studied with protons, neutrons and X-ray tests.
