Dispersion Studies on Multimode Polymer Spiral Waveguides for   Board-Level Optical Interconnects
  Dispersion studies are conducted on 1m long multimode polymer spiral waveguides with different refractive index profiles. Bandwidth-length products >40GHzxm are obtained from such waveguides under a 50/125 um MMF, indicating the potential of this technology.
