Abstract :
Guided-wave directional couplers having good polarisation-maintaining characteristics have been made in glass and assembled with polarisation maintaining fibre arrays fabricated by a novel technique using capillaries on a V-grooved substrate. The extinction ratios of the output ports were over 31 dB for waveguide chips and 26 dB for fibre array-assembled devices, respectively.
