The famous min-cut, max-flow theorem states that a source node can send a commodity through a network to a sink node at the rate determined by the flow of the min-cut separating the source and the sink. Recently it has been shown that by linear re-encoding ...

A new technique for real-time processing of arbitrary optical signals is proposed and experimentally demonstrated. A parametric processor was used to form multiple signal copies, synchronize intercopy delays, and perform simultaneous sampling of spectrally ...

700nm parametric conversion in silica fiber from near-infrared to short-wave infrared band is reported for the first time. The conversion efficiency in excess of 40dB was measured between 1300nm signal and 2000nm idler band. ...
Communications is about conveying information from one point to another subject to certain performance constraints. The information is assumed to be generated by a source and may, for example, represent a voice waveform, the reading of a thermal sensor, or ...
For a class of sensor networks, the task is to monitor an underlying physical phenomenon over space and time through an imperfect observation process. The sensors can communicate back to a central data collector over a noisy channel. The key pa- rameters i ...

In the Shannon-theoretic analysis of joint source-channel coding problems, achievability is usually established via a two-stage approach: The sources are compressed into bits' and these bits are reliably communicated across the noisy channels. Random codin ...

All-optical multicasting of a 320-Gb/s intensitymodulated return-to-zero signal with subsequent simultaneous sampling by a single parametric gate is experimentally demonstrated. The architecture used a two-pump broadband fiber-optic parametric amplifier fo ...

We consider source coding with a fidelity criterion, channel coding with a channel input constraint, and the combined problem of reproducing a source across a noisy channel. All three cases face a similar tradeoff between resource and performance, and the o ...
