Abstract
Method and system are disclosed for stable, multi-wavelength continuous wave (CW) generation using fiber-based supercontinuum and spectrum-slicing of its longitudinal modes. The continuum generated is coherent and stable, making it an attractive alternative as a spectrally-sliced source for continuous, multiple wavelength channels. A 140 nm wide supercontinuum with a 10 GHz repetition rate is generated in <30 meters of fiber. To obtain CW channels with 40 GHz spacing, time-domain multiplexing and longitudinal mode slicing are utilized. To obtain stable, continuous wave operation, short-fiber supercontinuum generation and a pulse interleaving method are utilized. The invention may be utilized as a broadband wavelength-division multiplexed source.
