Abstract:
A photonically-sampled electronically-quantized analog-to-digital converter generates an optical signal comprising a series of optical pulses. The optical signal is split into a first and a second optical path. The split optical signal is detected in the first path and then the detected optical signal is converted to a reference digital signal. The split optical signal in the second path is modulated with an input RF signal and a plurality of demultiplexed RF-modulated optically-sampled signals is generated from the modulated optical signal. The plurality of demultiplexed RF-modulated optically-sampled signals is then pulse broadened, detected, and converted to a plurality of sampled-RF digital signals. The reference digital signal and the plurality of sampled-RF digital signals are digital signal processed to generate a digital representation of the input RF signal.

Claim (Index 1):
A photonically-sampled electronically-quantized analog-to-digital converter comprising:\n a) an optical transmitter that generates an optical signal comprising a series of optical pulses; b) an optical splitter having an input that is optically coupled to an output of the optical transmitter and a first and second output; c) a reference optical detector having an optical input that is directly coupled to the first output of the optical splitter so that the series of optical pulses propagate in a path directly to the reference optical detector and having an output that is electrically connected to a reference analog-to-digital converter that generates a reference digital signal that represents the optical signal; d) an optical modulator having an optical input that is coupled to the second output of the optical splitter and having an RF input that receives an input RF modulation signal, the optical modulator generating an RF-modulated optically-sampled signal at an output that is coupled to an input of an optical pulse demultiplexer that generates a plurality of demultiplexed RF-modulated optically-sampled signals at a plurality of outputs; e) a plurality of optical detectors, an input of a respective one of the plurality of optical detectors being optically coupled to an output of a respective one of the plurality of outputs of the optical pulse demultiplexer, an output of each of the plurality of optical detectors being electrically connected to an input of a respective one of a plurality of signal analog-to-digital converters; and f) a digital signal processor having a plurality of inputs, a respective one of the plurality of inputs of the digital signal processor being electrically connected to a respective output of the plurality of signal analog-to-digital converters and having a reference input electrically connected to the output of the reference analog-to-digital converter, the digital signal processor generating a digital representation of the input RF modulation signal, wherein the digital signal processor uses the reference digital signal to provide an improved signal integrity of the digital representation of the input RF modulation signal.
