Polymer Optical Waveguide Chip: New Tool for Simple Evaluation of Optical Parameters of Waveguide Elements

A polymer optical chip consisting of 45°-angled cut straight waveguides, Y-splitters, and S-bend waveguides was designed and fabricated to examine a simple evaluation of multimode waveguides. Appropriate input condition was investigated for standardization of an evaluation method of optical characteristics of multimode waveguides.

Simple evaluation method of multimode polymer optical waveguides for next generation FTTH application

Polymer optical waveguide devices are getting popular for next generation FTTH application. In order to accelerate the development of polymer optical devices, evaluation of waveguide characteristics should be speeded up. Polymer optical chip containing a combination of 45°-angled cut waveguide, Y-splitter and S-bend structures was designed and fabricated for simple evaluation of multimode waveguides. Input launching such as light source, mode scrambler was investigated for reliable measurement.
