To improve the data rate in laser communication systems, a new modulation scheme, which uses the photon polarisation property, is proposed. Performance analysis and Monte-Carlo simulation are made, considering both non-turbulent and heavy-turbulent atmospheric conditions. The simulation results show that the data rate is twice as much as that of pulse-position modulation in a broad range of optical link efficiency.
