Fabrication of polymer waveguides using a molding process

Abstract
Polymer waveguides are successfully fabricated by a simple method, which is incorporated with a lithography-galvanic (LIGA)-like and micromolding process. The refractive index of the UV polymer used in these experiments is changed by an extremely low electric field. The measured propagation loss is 0.32dBcm for 1.3μm and 0.30dBcm for 1.55μm. This process is easy, simple, and suitable for mass production.
