Abstract

An apparatus comprising a dispersive fiber optical loop for delaying a first and second sideband, relative to each other, of a light modulated by a radio frequency signal to create a pair of pulses, a coupler for tapping a replica of the pair of pulses from the loop; and an auto-correlation module, coupled to the coupler, for correlating the replica of the pair of pulses with each other.
