Abstract:
Methods, systems and devices for amplitude coherent detection for pulse amplitude modulation (PAM) signals are described. One method for high-speed and high-capacity optical communication includes modulating an input signal based on pulse amplitude modulation, performing a pre-distortion operation on an output of the modulating, filtering an output of the pre-distortion operation using a pulse shaping filter, and transmitting an output of the filtering using intensity modulation, where the intensity modulation includes an equally-spaced amplitude distribution. Another method includes receiving an optical signal, performing a coherent detection operation on the optical signal, where the coherent detection comprises an equally-spaced amplitude distribution, converting an output of the coherent detection operation from an optical domain to an electrical domain by digitizing the output, filtering an output of the digitizing using a pulse shaping filter, and demodulating an output of the filtering using a pulse amplitude modulation demodulator.

Claim (Index 20):
