Abstract: We demonstrate a multilevel amplitude regeneration experiment for non-return-to-zero 4-level pulse amplitude modulated (NRZ-PAM4) signals in the proposed polarization-orthogonal continuous-wave-light-assisted nonlinear-optical loop mirror (PC-NOLM) subsystem. A uniform regenerative behavior including the same noise-suppression efficiency and… read more here.

Abstract: We propose a novel phase-preserving multilevel amplitude regenerator scheme by cascading two nonlinear-optical loop mirrors (NOLMs) with an intermediate optical phase conjugator (OPC) stage. Joint parameter optimization of the two NOLM units has been carried… read more here.
