Fig. 4: Combs in the CI topological phase, with θA = 0.3π, θB = 0.01π.
From: Floquet topological dissipative Kerr solitons and incommensurate frequency combs
a, b The band structure and the linear power absorption spectrum of the lattice show two edge bands and three bulk bands. c Pump power in the input-output ring as a function of pump frequency. d Intensity distributions in the lattice, at time instances separated by δt = 8τR, show the generation of a single soliton in each alternating ring at the edge of the lattice. This soliton molecule state appears stationary in the lattice. e Comb output in the time domain shows pulses repeating every τR. f–h Comb output in the frequency domain shows oscillation of only a single edge mode (the pumped mode).
