Abstract:
A multi-wavelength light source for outputting light comprising a plurality of individually modified wavelengths, comprising:wavelength demultiplexing means for demultiplexing input light into a plurality of different wavelengths;a plurality of optical amplifying means each for individually amplifying one of said different wavelengths from said wavelength demultiplexing means;a plurality of splitting means each for splitting an optical output from an associated one of said optical amplifying means;first wavelength demultiplexing means for wavelength-multiplexing first optical outputs of said splitting means and supplying the multiplexed output to said wavelength demultiplexing means;a plurality of optical modulators capable of individually modulating second optical outputs of said splitting means; andsecond wavelength multiplexing means for wavelength-multiplexing outputs of said optical modulators.
