For the first time experimental bit error rate curves are presented for an optically preamplified direct detection differential phase shift keying (DPSK) communication link. DPSK offers ̃6 dB peak power sensitivity improvement over more traditionally optically preamplified on/off keying (OOK). Using an erbium doped fibre preamplifier, a fibre Fabry–Perot filter, an optical DPSK demodulator consisting of a fibre-optic Mach–Zehnder interferometer with a 1 bit differential delay, and a balanced receiver, a sensitivity of 116 photon/bit was obtained. To the authors' knowledge these results represent the first demonstration of optically preamplified DPSK with better sensitivity than previously reported multigigabit per second heterodyne DPSK and ̃3 dB more sensitivity on a peak power basis than previously reported preamplified OOK systems.
