  • Abstract
    Polarisation characteristics of the fused-taper-twisted single-mode-fibre coupler as a quarter-wave device are reported for the first time. In the case that circular polarisation is launched into the input port of the fused-fibre coupler, linear polarisation was observed at two output ports of the coupler, and an extinction ratio of about 30dB was obtained.
