A spectral sliced multiwavelength laser source which utilizes supercontinuum generated in a high nonlinear dispersion
flattened holey fiber(HNL-DF-HF) and spectral slicing in an arrayed waveguide grating has been demonstrated. All 32
channels exhibit almost constant pulsewidth, the channel separation is 100GHz, and crosstalk of the adjacent channels is
more than 25dB.
