Abstract :
The authors describe an implementation of the polarisation diversity detection technique for coherent heterodyne communications which maintains the total IF amplitude at a constant level, irrespective of fluctuations in the state of polarisation of either the signal or local oscillator optical fields at the output polarisation beam-splitter.
