We propose an efficient synchronization scheme for two coupled chaotic systems consisting of synthetic temporal lattices. By directly coupling the feedback circuits of two identical temporal systems via a variable optical coupler, we establish a bidirectional and tunable synchronization mechanism. The synchronization is governed by a well-defined coupling angle, enabling precise control over performance and convergence speed without stringent initial condition matching. The system supports high-quality intermittent synchronization and features a specific coupling condition for rapid convergence. The scheme is inherently scalable to multi-system networks. This work provides a practical and flexible platform for robust synchronization, with potential applications in secure optical communications.
