Modular and Re-Configurable Parametric Wavelength Interchanging Cross-Connect Architectures

Abstract

We report on a new technique that allows for modular expansion of strictly transparent wavelength interchangeable cross-connect utilizing parametric wavelength converters based on four-wave mixing or difference frequency generation. The proposed technique results in cost effective cross connect architectures with fewer components than other frequently proposed designs. It will be shown that employing FWM-based converters results in reconfigurable and simple to fabricate architectures.
