Providing a common broadcast channel in a WDM (wavelength division multiplexed) system is accomplished by applying a pulsed light source to a dispersive delay line, and also applying the light source to each of M delay lines, such that the Mth delay line has a delay of (M-1) time slots, where M is a nonnegative integer representing the number of time slots to be provided for the broadcast channel. The dispersive delay line spreads the spectrum of the pulsed light source across the desired bandwidth of the WDM system to provide a wide-spectrum signal, and this wide-spectrum signal may then be modulated to provide a plurality of WDM channels. The M delay lines provide delayed pulses that may be modulated to provide a common broadcast channel for reception on a plurality of WDM receivers.
