摘要： A method for transmitting and receiving a radio frequency (RF) signal over an optical channel is described, where a nonlinear optical harmonic generation device is used to increase the system performance. The RF signal is phase modulated onto an optical carrier. The received optical carrier propagates through a nonlinear optical harmonic generation device, which increases a phase modulation depth at the harmonic wavelength. This larger modulation depth can be used to achieve larger gain. By photo-detecting both the fundamental and the harmonic optical wavelengths, then properly scaling and subtracting the two photo-detected signals, the enhanced modulation depth at the harmonic optical wavelength can be used to cancel out unwanted nonlinear distortions thereby linearizing the measured RF signal. The method uses a phase-to-amplitude conversion device to change phase modulation into amplitude modulation, and is compatible with phase-to-amplitude devices that perform photonic down-conversion thereby allowing for reduced bandwidth photo-detectors.

摘要： A system and method for measuring the temporal delay an optical signal experiences along a path is provided it uses single photon sensitive detectors and multiple optical pulse rates. The multiple optical pulse rates are chosen to allow each to be isolated in post-processing even if only a single detector is employed. The detectors can be time-gated at a repetition rate synchronized but different from the optical pulse rates, including the use of a pulsed-pump up-conversion detector. The pulse rate choice allows improved performance, including an extension of the unambiguous temporal delay range. The ability to isolate the pulse rates can also be used for measuring multiple path delays simultaneously or for spectrally resolving path characteristics without requiring the use of spectral filtering. The post-processing function can be segmented to include an initial signal quality estimation step so further processing can be aborted if it is unlikely to succeed.

摘要： An interferometer used for modulating an optical signal with an electrical signal is described, where the optical signal can be subsequently detected so as to sample and digitize the electrical signal. Nonlinear optical elements can be located inside the interferometer to reduce the minimum detectable electrical input signal size. The interferometer can contain more than two arms to improve the tolerable dynamic range of the electrical signal. In some cases some outputs of the interferometer are dependent on the electrical input frequency while others have minimal frequency dependence, thereby allowing the frequency of the input electrical signal to be measured more easily. Ideally the modulator operates in a push-pull mode with a single electrode for the input electrical signal. Such a modulator can be constructed by using appropriate optical delay elements.

摘要： The invention is related to phase detection in lidar systems using single photon detectors (SPDs). The frequency at which the SPDs are time gated is related to but not an integer multiple of the frequency of the transmitted optical pulses. Each return optical pulse arrives with a particular temporal position with respect to the nearest gate, and thus is detected with a related detection efficiency. The SPD output can be segmented into multiple time-multiplexed signals whose relative detection efficiency reveals the phase of the optical return pulses, and no such phases have negligible detection efficiency for all the time-multiplexed signals. To mitigate the impact of afterpulsing and other saturation effects, when a first optical pulse is detected with high detection efficiency the next optical pulse that is detected with high detection efficiency is separated by a time period about equal to or greater than the detector dead time.

摘要： Apparatus and method for a secure communication network using AlphaEta quantum encryption is provided. A polarization insensitive optical receiver based on a 90 degrees hybrid coupler is used for the detection and digitization of optically encrypted signals. Once digitized, such signals can be decrypted, stored, or re-transmitted over arbitrary media such as using RF wireless means. Alternatively, the signal can be generated directly for transmission over RF wireless nodes.

摘要： A secure optical communication system and method are disclosed. Short optical pulses are first modulated with data, then dispersed in time so that they spread out over multiple bit periods, then the desired code is applied to the dispersed pulses. The encoding may include frequency shifts or phase shifts or other. The dispersed optical symbols overlap in time so an applied code chip thus acts on multiple symbols simultaneously. There are generally multiple code chips per dispersed symbol. The coding device does not need to be synchronized to the data rate. Multiple wavelength division multiplexed channels may be encoded simultaneously. The signal propagates to a decoder that is synchronized with encoder to apply a complementary code thereby canceling out the effect of the encoder. The encoder and decoder can be realized by varying the wavelength of an optical pump to a parametric amplifier, allowing for a wide-band frequency shift.

摘要： A single photon detection system and method are disclosed which have a control block for helping to monitor and optimize performance, especially at high detection rates. The system is based on photon detectors constructed with avalanche photodiodes (APD) gated in time to operate in the Geiger mode. An electrical reference frequency is generated which is subtracted from the APD output in order to better isolate the breakdown event. The resulting signal is sampled and analyzed to allow the control unit to optimize the magnitude and phase of the electrical reference frequency. The control unit may also change the gate pulse shape and phase, including by the use of a digital-to-analog converter. The gate pulse can be shifted off an input optical pulse so as to estimate dark count rate, or shifted to measure a reference input signal to estimate detection efficiency.
