We present an application of femtosecond laser pulses that is not directly related to high speed, but rather makes use of the large spectral bandwidth of these pulses to address a systems issue in wavelength-division-multiplexed (WDM) communication links. One inherent difficulty of currently proposed WDM systems is the need for multiple lasers operating at different wavelengths, which hence have to be wavelength-selected and stabilized at that particular wavelength for years to come. We demonstrate a WDM system based on a single short-pulse laser source that covers all WDM channels simultaneously, hence eliminating many of the source problems of conventional WDM systems.
