Hybrid integration of optical polymer waveguides and 25 GHz photo detector arrays
Abstract
To summarize, we have demonstrated hybrid integration of polymer waveguides and photodetectors using a vertical coupling scheme. The easy-to-fabricate, yet efficient 45° mirror is one of the key features of the polymer platform. Integrated 4-channel arrays with 25 Gb/s capability showed low insertion loss, good responsivity, fairly low crosstalk and back-reflection, which will allow their application to advanced receiver architectures for 100 Gb/s optical transmission systems.
