Abstract

We report here a multiwavelength light source using semiconductor mode-locked lasers with the optical frequency spacing of 100 GHz. In this light source, a mode-locked semiconductor laser was used for the original light source, which gave multimodes with constant frequency spacings. The output from the mode-locked laser was fed into silica-based arrayed waveguide grating filter (AWG) with the free spectral range of 100 GHz and 16 channels of input/output ports.
