Paper Abstract

In this paper, we experimentally demonstrated a free space optical communication system transmission based on continuous wide-spectrum laser at 10Gbit/s over 1km simulated atmospheric channel. The wide-spectrum laser is part of supercontinuum generated by using a self-made picosecond mode-locked laser based on Raman gain solution effect to pump a dispersion compensation fiber which dispersion coefficient are D=-135ps/nm ⋅ km@1550nm. A 10Gbit/s NRZ signal was then modulated on the wide-spectrum laser and transmitted into a tunable simulated atmospheric turbulence pool which can simulate atmospheric turbulent intensity up to 0.59cm of coherent length. Scintillation intensities and bit error rates of transmission based on wide-spectrum laser and narrow linewidth laser were compared. The results show that communication sensitivity reached -10.98dBm at FEC limit. which has 1.53dB improvement comparing with FSO communication system using narrow linewidth laser under weak turbulent condition.
