Abstract: | In order to meet the requirements of the multi-wavelength light source of large-capacity, high-speed, long-distance optical communication system, we researched the multi-wavelength light source based on super-continuum (SC), analyzed the main factors in the SC generation, such as dispersion, nonlinear effects. The SC simulation and optimization around the input pulse width, peak power, fiber length, non-linear coefficient parameters for analysis. The optimized results: SC input achieved 25 GHz repetition rate, amplified by high power EDFA, input average power did not exceed 33 dBm. The output of the SC 3 dB bandwidth was greater than 70 nm, after AWG, output 320 wavelengths, wavelength spacing is 0.2 nm (25 GHz), the signal-to-noise ratio was greater than 30 dB. |
