✦ Synopsis

A coherent, transparent optical communication system has been developed for free-space lasercomm terminals. The laser synchronisation scheme has been chosen such that the transmission of either an ensemble of subcarrier-modulated signals or of a binary baseband signal is equally possible. By using double-sideband modulation and an average-powerlimited booster amplifier, the link capacity for subcarriermultiplexed transmission approaches that of a homodyne PSK transmission system to within 0.5 dB.

We propose a high carrier suppression double sideband modulation technique using a Mach-Zehnder modulator (MZM) and an integrated polarization state rotation filter (PSRF), which is designed to improve the carrier suppression ratio. With the functions of MZM and PSRF, about 30 dB carrier suppression
