Low-loss Light Coupling Design for Multimode Polymer Optical Waveguides with VCSEL Light Sources

摘要

In this paper, we focus on the coupling loss of polymer waveguide based optical links, which exhibits a serious impact on the power budget in such a short-reach link. In particular, the optimum core size of polymer waveguides for the low coupling loss with VCSELs and PDs with small effective area is investigated both theoretically and experimentally.
