We experimentally validate our works in recurrent optical spectrum slicers for dispersion compensation in IM/DD links, exploiting programmable photonics. We equalize 50 km of 64 Gb/s PAM-4 transmission in C-band, with simple digital feedforward equalization, achieving BER below 1x10-2with two nodes.
