Abstract
A photonic analog to digital converter (pADC) includes an electronic I/Q generator, an optical sampler, and an optical detector. The electronic I/Q generator is configured to receive an RF signal and to generate an electronic in-phase signal I and an electronic quadrature-phase signal Q based on the received RF signal. The optical sampler includes one or more optical intensity modulators configured to receive the electronic I and Q signals from the electronic I/Q generator, and to modulate optical pulses to provide modulated optical I and Q signals based on the received electronic I and Q signals from the electronic I/Q generator. The optical detector includes a plurality of photodetectors, and is arranged to receive the modulated optical I and Q signals from the optical sampler and to convert the modulated optical I and Q signals into modulated electronic I and Q signals.
