Actually I am implementing an analog to digital converter in which only sampling is done photonically.
After I sample electrical signal with an optical pulse generator using MZM modulator, I convert the optical analog signal to an electrical signal using a photodiode. Now I get sampled electrical signal and now I want to digitize its amplitude. And so I am looking for any component that takes sampled analog electrical signal and digitizes its amplitude to turn it into a digital electrical signal. Is that possible ?
