Nonlinear effects are one of the main causes of pulse degradation in high bit-rate transmission systems and several architectures have been proposed to compensate them by means of optical phase conjugation. In this letter, a new method to exploit an optical phase conjugator for nonlinearity cancellation is disclosed. The proposed method is simpler than those previously described in literature and allows a relevant improvement of systems performances. Link-design rules are analytically studied; moreover, their effectiveness is numerically demonstrated for different applications. This technique can apply to any bit rates and modulation formats.

Abstract
Nonlinear effects are one of the main causes of pulse degradation in high bit-rate transmission systems and several architectures have been proposed to compensate them by means of optical phase conjugation. In this letter, a new method to exploit an optical phase conjugator for nonlinearity cancellation is disclosed. The proposed method is simpler than those previously described in literature and allows a relevant improvement of systems performances. Link-design rules are analytically studied; moreover, their effectiveness is numerically demonstrated for different applications. This technique can apply to any bit rates and modulation formats.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
