Abstract

We propose star-coupling based on large-core polymer optical fibers. Mixing rods with tapered and untapered ends are employed to form 1 X 7 and 7 X 7 broadcast and mixing couplers. We found that excess loss and coupling uniformity are mixing length dependent and that of a 15 cm length tapered mixing-rod based 1 X 7 coupler can have a 1.72 dB excess loss and a 1.0 dB uniformity. The average excess loss and uniformity for a constructed 18 cm mixing-rod length 7 X 7 star-coupler are found to be 1.38 dB and 1.92 dB, respectively.
