Principle of optical arbitrary waveform characterisation through spectral slicing. (Left): A broadband signal under test is demultiplexed using a wavelength division demultiplexer and detected using the lines from a frequency comb source. (Right): Phase and amplitude alignment principle. The sub-bands have an overlap region (shaded spectrum) due to the finite response of the demultiplexing filters.
