Abstract

This paper investigates the problem of designing scalable and cost-effective wavelength division multiplexing (WDM) optical interconnects. We propose a new design for WDM optical interconnect that has several advantages over existing designs. First, wavelength conversion occurs between two predefined wavelengths. This not only eliminates the need for expensive wide-range wavelength converters, but also ensures high scalability as the conversion range is independent of the number of the wavelengths in the system. Second, the new design requires a smaller number of switching elements compared to most of the recent best interconnect designs.
