Development and testing of a novel all-optical signal regeneration technique

In this paper, a new all-optical signal regeneration technique is designed by integrating the degenerated Four Wave Mixing (FWM) and designed optical locked signal mechanism. The developed technique is tested over three noisy 15Gb/s DPSK test signals via simulation. These signals are configured with different wavelengths and inclusion of different level of phase noises. The noisy DPSK test signals carried out approximate BER of 10−5 at power penalty of −6 dBm. The developed all-optical signal regeneration technique yields approximate BER of 10−12 at −14 dBm power penalty for three DPSK distorted test signals. The developed technique will be helpful to improve the performance of existing regeneration systems.
