Abstract
A WDM optical wavelength converter for converting modulated radiation at a first WDM wavelength channel (.lambda..sub.1) to corresponding modulated radiation at another WDM wavelength channel (.lambda..sub.2) comprises: a semiconductor laser (e.g., a sampled grating distributed Bragg reflector SGDBR device) integrated with a semiconductor optical amplifier (SOA). The converter is characterized in that the laser is wavelength tuneable over at least a plurality of wavelength channels and preferably all wavelength channels.
