Summary:
We numerically investigate chaos synchronization property with delayed feedback and coupling. We focus on the different synchronization state for high and low frequency components by applying a low-pass filter on the change of each laser dynamics between chaotic oscillations and low-frequency fluctuations (LFF). We demonstrate dynamics-dependent synchronization, where the occurrence of in-phase and anti-phase synchronization at different frequency components is determined by the chaotic and LFF dynamics. These numerical results agree well with our previous experimental results in a photonic integrated circuit with mutually-coupled semiconductor lasers.
