概要 | 主筆 We introduce an optical amplifier to implement asymmetric feedback, and we change the feedback strength of one of the two coupled lasers to observe dynamics-dependent synchronization.In-phase synchronization is observed for the original signals, while anti-phase synchronization is found for the low-pass-filtered signals, in the presence of low-frequency fluctuation dropouts. We analyze dynamics-dependent synchronization by observing temporal changes in the short-term cross-correlation and the local optical frequency detuning. |
