Abstract
An original coherent transmission technique with polarisation modulation and (two-channel) differential heterodyne detection is demonstrated. In a preliminary experiment, sensitivities within 4dB of the shot noise limit have been achieved. High immunity to laser phase noise is obtained.Keywords
