Fabrication of Multimode Polymer Optical Waveguides by Using UV Curable Resins and Transfer Molding Process

摘要

Multimode polymer optical waveguides have been fabricated by using the transfer molding process. By using this simple process and our newly developed UV curable materials (EFIRON~(~R) WR series), large core size (45x45μm) waveguides for multimode application were easily prepared. Resulting waveguides exhibited very smooth surface profile and square cross section of core dimension. The propagation loss of fabricated waveguide was measured to 0.2dB/cm at 850nm.
