Fig. 4

a Normalized optical power spectrum of an intensity-modulated optical carrier, centered at 1550 nm, with a MNIST image and a 10 GS/s pixel rate, b Power responses from the drop ports of five SmartLight-implemented OSS nodes, set as to uniformly “slice” the single side-band of the optical spectrum.
