Abstract

We report for the first time, 3D tapered polymeric waveguides fabricated by the compression-molding technique. Compression-molded polymeric waveguides presented herein provide a feasible solution to bridge discrete optoelectronic devices having the apertures of a few microns to hundreds of microns in both horizontal and vertical directions. One-cm long tapered channel waveguides with the cross-sections of 5 micrometers X 5 micrometers at one end and 100 micrometers X 100 micrometers at the other end were fabricated. These polymeric channel waveguides have a propagation loss of 0.5 dB/cm when the 632.8 nm He-Ne laser light is coupled from the small end to the large end and of 1.1 dB/cm when coupled from the large end to the small end. By confining the energy to the fundamental mode, when coupling from large end to the small end, a low-loss packaging can be achieved bidirectionally.
