About Polymer Waveguide

Polymer optical waveguides are flexible or rigid optical circuits which can be used in various application for data transmission, optical light guide.

Merits of Polymer Waveguide

1. Thin, Flexible

  • Wiring at narrow space
  • Fabricating thin and compact module

2. Shuffler of Optical Signal Line

  • Only 1 layer waveguide to achieve shuffling of optical signal
  • Fabricating splitter pattern waveguide, and tapering pattern one, and so on easily

3. High Density Optical Signal Line

  • Line width/Space width = 50um/10um
  • Lower space of input/output connection than fiber one
  • Fabrication of a micro-mirror each optical line (core/channel)
