Abstract
A photonic analog-to-digital signal conversion system can utilize an optical phase modulator configured to receive a first signal and a first optical pulse signal and to provide an optical phase—modulated pulse signal. A photonic processor can be configured to receive the optical phase—modulated pulse signal and the optical pulse signal and to provide an electronic first demodulated signal and an electronic second demodulated signal. A first comparator can be configured to receive the electronic first demodulated signal and provide a first compared signal, and a second comparator can be configured to receive the electronic second demodulated signal and provide a second compared signal. At least one logic circuit can be configured to receive the first compared signal and the second compared signal.
