Experimental Research on 10 Gb/s All-Optical Logic Gates with Return-to-zero Data in High Nonlinear Fiber
(0) A novel scheme to realize all-optical logic gates is proposed bases on nonlinear polarization rotation (NPR) in high nonlinear fiber (HNLF). Two optical signals A and B with return-to-zero data format are injected into the HNLF together with a continuous wave C. Thanks to the optical power variation in HNLF, nonlinear birefringence will be induced between the two polarization axes. Both the optical signal and continuous wave are filtered out at the output of HNLF. By adjusting the optical power and polarization of the optical signal as well as the polarization of the polarizer with respect to the polarization of optical signal/continuous wave, multiple all-optical logic gates can be realized. The theoretical analysis of the optical logic gates based on NPR in HNLF is provided. And we demonstrated the feasibility of the scheme by realizing all optical and not nxor .
