Abstract:
A photonic feedforward analog-to-digital converter (ADC) is provided. According to one aspect of the invention, the signal to be digitized is applied to only one electro-optic modulator. High speed is achieved by taking advantage of the fundamental property of a Pockels Cell to control wave polarization using the electro-optic effect. In a further aspect, once a bit is determined, its state is fed forward to the next least significant bit to aid in determination of the next lower bit. This nonlinear feedforward aspect of the ADC provides simplicity of its architecture.

Claim (Index 5):
A method of operating a photonic feedforward analog-to-digital converter, comprising:\n modulating a source optical signal based on an analog electronic signal to produce a modulated optical signal, the modulated optical signal having a value of a characteristic that is changed relative to the value of the characteristic of the source optical signal based on the analog electronic signal; in each stage of a plurality of stages:\n setting the value of a digital output of the stage, based on the value of the characteristic of an optical signal input to the stage relative to a stage threshold value, wherein the optical signal input to a first stage of the plurality of stages is the modulated optical signal; \n selectively modifying the characteristic of the optical signal input to the stage based on the value of the characteristic of the optical signal input relative to the stage threshold value; \n feeding forward the selectively modified optical signal as an input to a subsequent stage of the plurality of stages; and \n combining the values of the digital output of the plurality of stages to produce a converted digital equivalent value of the analog electronic signal.
