Abstract
In this paper, we investigate a coherent optical wireless communication system, which is able to support tens of gigabits per second data transmission and suit for high speed indoor interconnection. The modulated optical signal is diverged by a diffuser, and it is collected and coupled into a digital coherent receiver. The transmission model is analyzed and simulated by taking reflection into account. We also experimentally demonstrate the indoor coherent optical wireless system at 25 Gb/s over 1 m transmission distance. Numerical and experiment results show that the indoor coherent optical wireless system is an attractive alternative for achieving high data rates.
