Abstract
A method of processing an optical input signal comprises transmitting the optical input signal through first and second signal paths, mixing the optical input signal with first and second local oscillator (LO) signals in the respective first and second signal paths to produce first and second electrical signals corresponding to different portions of a frequency spectrum of the optical input signal, and combining the first and second electrical signals to produce a coherent time-domain output signal.
