Simultaneous format conversion of parallel multichannel based on FWM in symmetric highly nonlinear fiber loop
Yueying Zhan, Min Zhang, Zhuo Liu, and Xue Chen
A parallel multichannel format conversion scheme for elastic optical networking based on four wave mixing (FWM) in symmetric highly nonlinear fiber loop (S-HNLF-L) is proposed and the performance is evaluated and discussed. Parallel four channels format conversion from quadrature phase shift keying (QPSK) to binary phase shift keying (BPSK) signals at 40 Gb/s is theoretically analyzed and simulated. The results are helpful for the format-adaptive elastic optical networks.
