We analyze the performance of adaptive field
conjugation array receivers in satellite downlink coherent laser
communications. We consider coherent fiber arrays consisting of
multiple subapertures, with each subaperture interfaced to a
single-mode fiber. We quantify how field conjugation processing
improves performance in the presence of turbulence, as
compared to a monolithic-aperture coherent receiver having an
equal total cross-sectional area. In general, the performance of
such a field conjugation adaptive should improve with an
increasing number of subapertures and, given a fixed collecting
area, the fiber array system can offer superior performance.
