Abstract
A photonic processor can include a first input for an amplitude-modulated optical pulse signal, a second input for an optical reference signal, and a plurality of stages. Each stage is configured to receive the amplitude-modulated optical pulse signal and a version of the optical reference signal. The version is amplitude attenuated in accordance with a position of the stage. Each stage is comprised of a reference path, a signal path, two couplers and a balanced photo detector. The first coupler receives the pulse signal and provides as stage pulse signal to the signal path coupled to a first input of the detector. The second coupler receives the version and provides a stage optical reference signal to the reference path coupled to a second input of the detector. The detector provides an electronic output signal corresponding to an amplitude relationship.
