In this paper we present an overview of all-optical generation of vestigial sideband (VSB) signals based on self-phase modulation (SPM) in semiconductor optical amplifiers (SOA) at 10 Gb/s and 40 Gb/s. An optical pump is used to saturate the SOA, avoiding self gain induced distortion. Operation with co- and counter-propagation of the signal and pump is experimentally assessed. Back-to-back sideband...
