Abstract

Kerr micro-resonator frequency combs exhibit a variety of nonlinear phenomena, most prominently the formation of dissipative Kerr solitons (DKSs). These solitons are critical for applications in frequency metrology, precision time-keeping and ultrashort pulse generation. Thus far all studies of DKSs have been limited to single cavities [1, 2] or two uncoupled cavities [3–5], though coupled dual microring resonators with the potential for generating DKS in both ring cavities have been demonstrated [6]. Inspired by multi-soliton interactions [7] and synchronization of coupled modelocked lasers [8], we numerically investigate the dynamics of DKSs in a network of coupled cavities. Given its scalable and phase sensitive nature such a system is expected to exhibit even richer nonlinear phenomena with the potential to enable new technologies.
