The performance of a multi-wavelength light source with precise optical frequency spacings of 100 GHz was demonstrated using a semiconductor mode-locked laser diode. All outputs were locked to the wavelength division multiplexing (WDM) optical frequency grids and peak intensity and side-mode suppression were larger than -15 dB and 15 dB in ten of the output channels. The measured bit error rate of the outputs showed dependence on the average received power. In seven of the output channels, sensitivity degradation was less than 3 dB compared with the distributed feedback laser. The results indicate that the multi-wavelength light source is suitable for WDM applications.
