1. A processor, comprising:

  • a phase modulator the photonic processor configured to receive a first electronic signal and an optical reference signal and provide a phase modulated optical pulse signal;

    an array of signal optical switches for receiving the phase modulated optical pulse signal and providing a set of time deinterleaved sampled phase modulated optical pulse signals;

    an array of reference optical switches for receiving a reference pulse signal and providing a set of reference time deinterleaved reference pulse signals;

    an array of optical demodulators each configured to receive a respective time deinterleaved phase modulated optical pulse signal of the time deinterleaved sampled phase modulated optical pulse signals on a respective signal path and a respective time deinterleaved reference pulse signal of the time de-interleaved reference pulse signals on a respective reference path, wherein each of the demodulators is configured to perform demodulation and to provide a respective optical demodulated signal;

    an array of photoconverters each configured to receive the respective optical demodulated signal and to provide a respective second electronic signal corresponding to the respective optical demodulated signal; and

    an array of track and hold amplifiers each for receiving the second respective electric signal and providing a respective deinterleaved electronic signal.
