Summary:
Broad laser chaos synchronization is very desired for its application in secure communication. Limited by intrinsic relaxation oscillation, the bandwidth of laser chaos is lower than 10 GHz. Many methods have been proposed and demonstrated to obtain broadband chaos by breaking the limitation of relaxation oscillation. However, the chaos synchronization becomes difficult. Here we demonstrate the generation and synchronization of broadband chaos in long-cavity FP lasers. Enhanced by modes beating in 1.5 mm-long-cavity FP lasers, the bandwidth of laser chaos is up to 37 GHz. By filtering multiple wavelength slices, multi-wavelength broadband chaos is obtained with synchronization above 0.98.
