ABSTRACT In this work we show how to implement all-optical shuffle multihop networks with network interface units presenting a general value of inputs and outputs and taking into consideration both dedicated and shared channels.

    ABSTRACT: The first complete nonlinear optical-loop mirror demultiplexing experiments including error-rate measurements are reported. Broadband demultiplexing of 16-, 32-, and 64-Gb/s, 2/sup 15/-1 data was performed using only semiconductor lasers. The penalty for demultiplexing a 64-Gb/s time-division multiplexed data stream to the 4-Gb/s fundamental rate was 2.2 dB at an error rate of 10/sup -9/. The switching pulse energy was 1.1 pJ.< >

    ABSTRACT: We describe a novel architecture for an all-optical time-domain chirp switch in which digital logic is based on timeshift keying. This architecture is a generalization of fiber soliton-dragging logic gates that have a switching energy approaching 1 pJ. By using solitons we separate the nonlinear chirping from the time shifting and, consequently, reduce the required phase shift during the nonlinear interaction. We discuss the scaling laws for energy and latency versus pulse width and show that the chirp switches have low switching energies for high-bit-rate applications.

    ABSTRACT: The effects of stimulated Raman scattering (SRS) and the self-frequency shift on soliton communication systems are analyzed. These effects impose stringent limitations on the maximum data rates that can be carried in such systems. The limitations arise as soliton amplitude or frequency fluctuations are translated into pulse position jitter after propagation along a fiber. Estimates of the maximum data rates in single-channel and multichannel soliton systems are obtained and are compared with data rates in linear direct detection systems. A single-channel soliton system can, in principle, carry data at a rate of between two and ten times faster than a simple, direct-detection, linear system. In a multichannel system, using data channels at different wavelengths, the advantages of using solitons are reduced
