Abstract
A method for transmitting an optical signal through a first channel and a second channel includes coupling the optical signal with a first pair of comb lines separated by a spacing frequency to create an optical signal copy that is spaced from the optical signal by the spacing frequency. The method also includes filtering a first slice of the optical signal and a second slice of the optical signal copy. The method also includes transmitting the first slice of the optical signal and the second slice of the optical signal through the first channel and the second channel, respectively. The method also includes stitching the first slice of the optical signal with the second slice of the optical signal copy to generate a stitched version of the original optical signal.
