Paper Abstract

A hybrid mode-locked semiconductor laser was demonstrated as a multi-wavelength light source for WDM networks. The laser simultaneously provides over 50 WDM channels spaced at 21.8 GHz (0.17 nm). Channel spacing is temperature independent and is determined by the modulating frequency applied to the absorber section of the laser, thus is very stable. The wavelength of the channels can be slightly tuned by injection current and/or temperature. We demonstrate dropping a WDM channel at a network node by using a Fiber Bragg Grating combined with a fiber coupler.
