Synchronization transmission of laser signals between networks with arbitrary topology within a finite time based on linear coupling strategy

Abstract

Two complex networks are constituted by the single-ring erbium-doped fiber lasers (SREDFLs), and the scheme of synchronization transmission of laser signals is designed based on a linear coupling strategy. Furthermore, the signal transmission between the laser networks can be synchronously realized within a finite time. According to the numerical simulation, it is found that each error tends to zero after a short oscillation, implying that the synchronization transmission of the laser signal between corresponding nodes belonging to different networks is achieved in a foreseeable time. Meanwhile, all the coupling coefficients are also fixed to zero while the synchronization transmission between the laser networks is realized. Therefore, the simulation results prove that the control strategy of finite-time synchronization transmission between the laser networks based on a linear coupling technique is feasible and efficient.
