Abstract: In exemplary embodiments, all-optical pattern recognition for an optical input signal is achieved by wavelength-converting the input signal and then passively correlating the wavelength-converted signal based on a specified data pattern. By performing wavelength conversion using a CW laser signal having wavelength stability greater than that of the input signal, errors resulting from wavelength sensitivity of the passive correlator can be reduced. By performing both wavelength conversion and OOK-to-BPSK format conversion prior to the passive correlation, limitations in the number of available OOK patterns can be avoided. By performing the passive correlation in a bi-directional manner, feedback signal can be generated to control the operations of the passive correlator and/or the laser signal source(s).

Abstract: An all-optical modulation format converter for converting optical data signals modulated in an on-off-keying (OOK) format to a phase-shift-keying (PSK) format. The OOK-to-PSK converter can be coupled to a delay-line interferometer to provide an all-optical wavelength converter for differential PSK (DPSK). The OOK-to-PSK converter can also be used in all-optical implementations of various functions, including, for example, exclusive-OR (XOR) logic, shift registers, and pseudo-random binary sequence (PRBS) generators.

Abstract: Methods and apparatus are provided for transmitting alternate-polarization phase-shift-keyed data. The output of a laser is modulated to optically encode electronic data using phase shift keying (PSK) to generate an optical signal. An alternate polarization PSK (APol-PSK) signal is generated by alternating the polarization of the optical signal using a modulator such that successive optical bits have substantially orthogonal polarizations.

Abstract: A communication system adapted to use wavelength (frequency) division multiplexing for quantum-key distribution (QKD). In one embodiment, a communication system of the invention has a transmitter coupled to a receiver via a transmission link. The transmitter has (i) a first optical-frequency comb source (OFCS) adapted to generate a first plurality of uniformly spaced frequency components and (ii) a first multi-channel optical modulator adapted to independently modulate each component of the first plurality to produce a quantum-information (QI) signal applied to the transmission link. The receiver has (i) a second OFCS adapted to generate a second plurality of uniformly spaced frequency components and (ii) a second multi-channel optical modulator adapted to independently modulate each component of the second plurality to produce a local-oscillator (LO) signal. Each of the first and second optical-frequency comb sources is referenced to a frequency standard such that the frequency components generated by these comb sources have substantially the same frequencies. The receiver employs a multi-channel homodyne detector adapted to process interference signals produced by combining the LO signal with the QI signal to ascertain quantum information carried by the QI signal.

Abstract: An optical pulse monitor (OPM) that determines an optical phase profile for a pulse train by (i) modulating the optical phase of pulses in the pulse train using a periodic waveform and (ii) generating a derivative of a spectrum of the resulting modulated signal with respect to the waveform's amplitude. In one embodiment, an OPM has a phase modulator that modulates the optical phase of pulses in a received pulse train using a periodic waveform supplied by a configurable drive circuit. The drive circuit temporally aligns the waveform with the pulse train to serially produce each of four selected temporal alignments. An optical signal analyzer measures a spectrum of the modulated signal generated by the modulator for each of these four temporal alignments and provides the four measured spectra to a processor. The processor uses the measured spectra to determine two spectrum derivatives with respect to the waveform's amplitude. The processor samples each of the spectrum derivatives at frequency points separated from one another by the frequency of the periodic waveform and uses these samples to obtain a series of complex values. The processor then calculates the optical phase profile for the pulse train based on the phase of a complex value obtained by summing the series.

Abstract: Method and apparatus for synchronizing two different types of modulators in an optical transmission system includes a first modulator generating an optical pulse train, a second modulator encoding data onto the optical pulse train, an optical filter resolving upper and lower modulation sidebands of the optical data and an analyzer measuring the optical power of modulation sidebands and converting the received optical power of the sidebands into a control signal for synchronizing the two modulators. A wedged etalon is the filter element selecting the USB and LSB from the optical data spectrum. The analyzer contains photo-detectors measuring the optical power of the filtered USB and LSB and an electronic differential amplifier producing a control signal based upon photo-detector output. The phase shifter, in response to the control signal, adapts the temporal delay of the first modulator to reduce differences between the power levels of the upper and lower sidebands.
