Precision assembly of polymer waveguide components for silicon photonic packaging

摘要

Silicon nanophtonics technology brings huge advances to telecom, datacom and computer communication. The use of this technology requires a cost effective method of optical input/output coupling with the external fiber cable. Use of the optical polymer waveguides enables a versatile coupling method. Because the optical signals are in a single mode, tighter positioning accuracy is necessary to realize a low loss coupling. We report the analysis of the alignment method of optical connector to connect the polymer and fibers and describe a new method to improve the positioning accuracy.
