Paper Abstract

An optical link over several kilometers between buildings or remote sites will have significantly reduced bandwidth in the presence of turbulent air, such as may be caused by convection from a heated earth surface. Bandwidth is decreased by amplitude and phase fluctuations due to the turbulence. This paper investigates the performance improvement in bandwidth by using a phase conjugate reflected beam for signal transmission. Weak fluctuations, consistent with the Rytov transformation, are assumed. A computer simulation is developed that uses a statistical model of the turbulent channel to assess the effectiveness of this approach.
