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.
