“…A WC can often perform multiple wavelength conversions simultaneously, although the mapping must follow a specific pattern [7][8][9][10][11][12]. Multiple stages of these WC devices can form a network to allow an even larger number of simultaneous wavelength conversions.…”

“…The device will simultaneously map all incoming wavelengths to their mirror images on the output link [8]. In this paper we focus on another type of space/wavelength cross-connect based on 2 × 2 wavelength exchange elements (WEEs), which can swap the wavelengths of their two inputs [9][10][11][12], but each input/output only carries one wavelength.…”

All-optical cross-connects need to perform switching not only in the space domain, but also in the wavelength domain. Switching in the wavelength domain requires wavelength converters (WCs), and WCs capable of simultaneously performing multiple wavelength conversions have been invented. We can use multiple stages of such WCs to form a wavelength exchange network to allow an even larger number of simultaneous wavelength conversions. However, WCs with a full conversion range are often difficult to implement. In the paper, we develop new techniques and theories that can reduce the conversion range requirement and still maintain the full connectivity of all-optical space/wavelength switches.
