PHOTONICALLY-ENABLED RF TRANSMITTER/RECEIVERTech for Transfer TTO 17-12-2015 This invention provides a photonically-enabled RF transmitter and/or receiver. It includes a detection system comprising a photonic module, an RF module and processing circuitry capable of accurate range measurements. It allows for multiple modes of operation of the system. The carrier frequency, the modulation technique and the processing and/or output that is to be provided by the system can be selected on the fly. It can be set up to support very wide ranges of carrier frequencies that can be modulated and processed in different ways in a relatively rapid fashion. Such a system may also be accurate enough to be useful for subscale radar testing, and be capable enough to be employed in the field. In addition, this system can be used as a flexible, tunable wideband signal generator or frequency source. Remote Sensing Optical Communications Tell me more |

FILTER-BASED DPSK COMMUNICATIONS SYSTEMTech for Transfer TTO 20-12-2015 This invention presents a filter-based method of demodulating differentially encoded phase shift keyed (DPSK) optical signals, such as commonly used binary-DPSK (DBDPSK) and quadrature DPSK (DQPSK) signals, that can achieve optimal receiver sensitivity. This approach, which combines filtering and differential phase comparison, can reduce the complexity and cost of DPSK receivers by obviating delay-line interferometer-based demodulation. This can improve receiver stability and reduce size, weight, and power, while maintaining the ability to achieve optimal communications performance. Optical Communications Tell me more |

PHOTONICALLY-ENABLED IN-FLIGHT DATA REORGANIZATIONTech for Transfer TTO 20-12-2015 This invention provides a new method of efficiently reorganizing data among a plurality of processing or storage devices communicating via a photonic channel. By constructing data transfer patterns in a shared photonic interconnect, rather than in dedicated reorganization hardware, data is reorganized while in transit, greatly accelerating the reorganization of data, and reducing the amount of power-consuming hardware necessary to achieve the task. This translates into well over an order of magnitude improvement in efficiency for the overall computer system. The electronic components are configured to modulate a light beam on a shared photonic interconnect and to detect the data according to a global schedule to reorganize data across the electronic components.

FSK MODULATOR OF OPTICAL SIGNALSTech for Transfer TTO 20-12-2015 Power efficient optical links are useful for a number of applications such as high-bandwidth free-space communications. The most efficient optical links utilize large-alphabet orthogonal modulation formats such as pulse-position modulation or frequency-shift keying (FSK) modulation. This invention features an FSK modulator for optical communications and a method for large-alphabet FSK modulation. The modulator and the method are based on filtering of a multi-tone optical source such as a mode-locked laser which provides a comb distribution of tones. The filtering can be done with a Mach-Zehnder interferometer or a microring resonator. The optical signal exiting the last filter includes only a single tone which corresponds to the symbol to be transmitted. Optical Computing Optical Communications Tell me more |
