A new proposal of photonic analog-to-digital conversion based on polarization modulator and polarizer

Abstract

In this paper, a novel photonic analog-to-digital conversion method is proposed, theoretically analyzed and numerically simulated. This method features simple configuration, because only one polarization modulator, several polarization controllers and several polarizers are required. Furthermore, this method mitigated the problem of bias-drift, which is common in some previous intensity modulating schemes.
