title: Polymer waveguide star coupler.
abstract: A polymer waveguide star coupler formed by the selective photopolymerization method is described. This polymer waveguide star coupler has low insertion loss independent of the core and cladding dimensions of the optical fiber. The six-port star coupler obtained, with input and output fiber arrays, had an insertion loss of 2.6 dB and a loss variation across the six ports of 1.2 dB at 0.84 microm.
