A Parallel Packet Switch (PPS) is a multistage switch aimed at building a very high-speed switch using much slower devices. A PPS in general has three stages. Several packet switches are placed in the central stage, which operate slower than the external line’s rate. Incoming packets are spread over the center-stage switches by demultiplexers at the input stage. Packets destined to each output ...
Westinghouse Electric Corporation Communication Division under NASA contract NAS3-25865 developed a proof-of-concept (POC) multichannel demultiplexer implemented as an acousto-optic radiofrequency (RF) spectrum analyzer. A detailed analysis of the experimental results indicate that the expected degradation caused by the acousto-optical channelizer is approximately 2.0-dB degradation at 10-5 bit...
This paper presents a new approach that exploits existing web applications and re-purposes them towards the multiscreen environment. For this purpose, a virtual splitting system is proposed. It consists of a generalized mapping technique that, contrary to previous works, automatically analyzes the application content based on a semantic or a visual criteria and prepares it for the splitting pro...
We report 10-ps correlated photon pair generation in periodically-poled reverse-proton-exchange lithium niobate waveguides with integrated mode demultiplexer at a wavelength of 1.5-mum and a clock of 10 GHz. Using superconducting single photon detectors, we observed a coincidence to accidental count ratio (CAR) as high as 4000. The developed photon-pair source may find broad application in quan...
Wavelength-division-multiplexing (WDM) networks with wide channel grids and bandwidths are promising for low-cost, low-power optical interconnects. Wide-bandwidth, single-band (i.e., no free-spectral range) add-drop filters have been developed on silicon using anti-reflection contra-directional couplers with out-of-phase Bragg gratings. Using such filter components, we demonstrate a 4-channel, ...
