摘要： A method of digitizing an analog electrical signal combines optical and electronic techniques in order to improve the resolution, sampling rate, input frequency range, or flexibility. It implements an optical interferometric modulator, which modulates an input optical signal by the input electrical signal combined with a calibration signal. A set of two or more photoreceivers receiving the output optical signals from the optical modulator produce output electrical signals, which are digitized and processed in a DSP to produce a digitized version of the electrical input signal, and a digitized calibration signal value is used to optimize the input electrical signal digitization. The method and the device can be used in many fields including instrumentation, communications, and imaging.

摘要： An optical device, suitable for use either as a coherent receiver or analog-to-digital converter, of optical phase modulated signals borne on a carrier. The signal is four-wave mixed with a pump to generate a non-linear comb of a series of harmonic components of the signal. The modulation-free carrier is also combined with the pump to generate an equivalent linear comb matched in frequency to the components of the non-linear comb. The harmonic and modulation-free components are linearly combined so they interfere in a pairwise manner, and then the interfered frequency components are separated out in an optical wavelength division demultiplexer into a plurality of frequency-specific optical output channels. A plurality of photodetectors connected to respective ones of the optical output channels then converts the analog values in each channel to respective electronic signals which are then digitized using a processor into binary digits using a thresholding process.

摘要： A time-stretched enhanced recording scope (TiSER) is described using time stretch analog-to-digital conversion in a real-time burst mode. A chirped optical signal is modulated in response to receiving segments of an input signal. The optical signal with its modulated input signal, is stretched through an optical medium and digitized to represent the waveform segment. TiSER provides ultra-fast real-time sampling within short segment bursts of the original input signal while providing an ability to detect non-repetitive events. Methods and apparatus are also described for providing real-time information about inter-symbol information (ISI), rapidly determining bit-error rates (BER), performing time-domain reflectometry (TDR), generating eye diagrams for serial data, facilitating digital correction of data, clock recovery, optical carrier phase recovery, and otherwise increasing the speed and/or accuracy of a diverse range of high-speed signal measurement and processing activities.

摘要： An all-optical combined serial-to-parallel and digital-to-analog convertor using standard WDM technology is realized. The system is based on bit interleaving and cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA). The optical system can operate on multiple-bit digital words at a very high bit rate. The analog output forms series of pulses with the amplitude of each pulse taking one of the eight discrete values. A low pass filter may be used to turn this bit stream into a continuous waveform, and thus arbitrary waveforms are generated. Unlike many current digital-to-analog converter designs, which double in size with each additional bit, the design presented here allows a linear growth in components, thus making higher bit systems practical.
