摘要： Examples of the present disclosure include the use of a topological system including an array of coupled ring resonators that exhibits topological edge states to generate frequency combs and temporal dissipative Kerr solitons. The topological edge states constitute a travelling-wave super-ring resonator causing generation of at least coherent nested optical frequency combs, and self-formation of nested temporal solitons that are robust against defects in the array at a mode efficiency exceeding 50%.

摘要： A topological photonic system configured as a robust source of indistinguishable photons pairs with tunable spectral correlations. The system includes a two-dimensional silicon-photonic ring resonator array configured to implement an anomalous-quantum Hall model that exhibits topologically robust edge states. Linear dispersion of the edge states ensures efficient and robust phase matching and tunability of the spectral bandwidth of photon pairs generated via spontaneous four-wave mixing. Spectral tunability is manifested in the temporal correlations in the Hong-Ou-Mandel interference between photons. The generated photon pairs are energy-time entangled.
