Abstract :
An optical cross-connect architecture based on wavelength routing is proposed. The design utilises an input waveband conversion stage followed by an arrayed waveguide grating (AWG) to enable optical switching and an output single wavelength conversion stage for wavelength assignment and regeneration. Arranging the AWG in feedback or foldback loop configuration the requirement for an output multiplexer is eliminated. The proposed solution supports wavelength switching granularity while offering reduced component requirements. Experimental and modelling results indicate very good system performance of the node as the output conversion stage offers regenerating characteristics.
