Abstract

In this paper, the combination of the initial positive chirp parameter of picosecond pulse, and the high non-linearity and low normal dispersion of photonic crystal fiber is studied to optimize the spectral flatness of continuum source for WDM system application. This continuum source is defined on the C-band of optical communication window and is capable of providing all the necessary channels after spectral slicing by an optical demultiplexer. If the initial source is delivered at repetition rate of 10 GHz, the obtained continuum allows to generate more than 32 channels spaced 100 GHz all centered at 1550 nm, where each channel is a pulses train has the same repetition rate than the initial source and suitable to modulate with modulation rate of 10 GHz to achieve data transfer rate of 10 Gb/s, the type of modulation format RZ-OOK was used for channels coding. In this context, the transmission chain of WDM communication system at 8.10 Gb/s is demonstrated.
