Optical Attenuation in Siloxane Polymer Waveguides

Polymer waveguides are attractive as an optical interconnect medium because they can enable high-density interconnects, and can be relatively easily integrated into organic board-level processes. The optical attenuation in the polymer optical waveguides is the key criterion used to evaluate their performance. This research study seeks to understand the effect of thermal curing and aging in siloxane polymer optical waveguides, and develop an optical attenuation model to ensure that the optical performance over extended field-use conditions is within the optical attenuation budget.
