Abstract
A 140 Mbit/s optical DPSK system experiment employing a 90 degree optical hybrid to achieve in-phase and quadrature detection is reported. The principle of the optical hybrid is outlined and the effect of polarisation misalignment on the optical performance is compared with that for standard homodyne/heterodyne detection.
