Abstract
Wavelength converters will be essential devices to exploit the full potential of the wavelength dimension in wavelength-division multiplexed (WDM) networks. Their most important use will be: to avoid wavelength blocking in optical cross-connects, to allow wavelength paths to be allocated on a link by link basis thereby facilitating simpler network reconfiguration, protection switching, and wavelength referencing, and to perform routing functions together with optical filters (e.g., space switching in optical switches;. Based on experiments, we discuss different candidates for efficient wavelength converters with attention to expected system requirements.
