Basic Evaluation of Polymeric Optical Waveguide Films Applied to Optical Interconnections

摘要

We have studied the basic optical and physical characteristics of polymeric optical waveguide films with S- shaped waveguides and 45 deg. C mirrors applied as multimode optical interconnection components. The core and cladding of the waveguide films were made of deuterated- polymethylmethacrylate (d-PMMA) and UV-cured resin, respec- tively. We evaluated the insertion losses of the waveguides, the crosstalk and the 45 deg. C -mirror losses in these waveguide films and demonstrated that they have low propagation loss. The shrink- age and thermal expansion of the polymeric optical waveguide films are also discussed because of the interest in improving module packaging.
