Fractal modulation has been traditionally investigated for use in wireless radio frequency applications, and shown to be beneficial in fading channels and multi-rate environments. Additionally, recent research with ultra-short pulses has shown that such signals are more resilient to water clouds and that they are transmitted through water clouds having an optical thickness as high as 3.2 (values typical of cumulus or stratocumulus clouds) using a modest laser energy of 7 mJ/pulse and 120 fs pulse duration. In this paper, we present a novel design for an FSO system that harnesses the merits of both fractal modulation and ultra-short laser pulse transmissions.
