Multilevel Amplitude Regeneration of PAM-4 Signals using a Nonlinear Optical Loop Mirror


Multilevel amplitude regeneration of return-to-zero PAM-4 signals is experimentally demonstrated using a single NOLM unit. The noise suppression capability at each amplitude level is characterized, and Q2-factor improvement of 0.92dB is achieved by optimizing input signal power and distortion strength
