DOI: 10.1016/j.ijleo.2019.02.012

Abstract: Abstract We theoretically analyzed and experimentally demonstrated the feasibility of optical single sideband (OSSB) signal generation based on multi-frequency phase modulation. The numerically calculated results show that OSSB signal can be efficiently generated with the… read more here.
