The use of optical buffer memories in packet switched networks is unavoidable to resolve contention problems. The fiber loop buffer memory of one slot delay is used in number of all optical switch architectures. In this paper, the behavior of such a loop memory is simulated and results are presented.

The realization of an all-solid microstructured optical fiber based on chalcogenide glasses was achieved. The fiber presents As(2)S(3) inclusions selected as low refractive index material (n = 2.4) embedded in a As(38)Se(62) glass matrix (n = 2.8). The single mode regime of the fiber was demonstrated both theoretically by multipole method calculations and experimentally by near field measuremen...

We consider all-to-all routing problem in an optical ring network that uses the wavelength-division multiplexing (WDM). Since one-hop, all-to-all optical routing in a WDM optical ring of n nodes needs ! w (Cn; IA; 1) = d 1 2 b n 2 4 ce wavelengths which can be too large even for moderate values of n, we consider in this paper j-hop implementations of all-to-all routing in a WDM optical ring, j ...

We propose an all-optical continuous-variable quantum teleportation scheme based on optical parametric amplifiers.
