Fig. 5: Forced oscillation of SC.
a Illustration showing force applied on SC. The moving potential field imposes a periodic force on soliton pulses, resulting in the forced oscillatory motion of SC. b Simulated intracavity angular position oscillation of 3 lattice sites from a 10-SC state. Simulated intracavity field envelope is shown in (c). The modulated background has a relative moving speed to SC, and SC vibrates around its equilibrium position with oscillating power. d, e Experimental (d) and simulated (e) optical spectrum (left panel), normalized soliton power trace (middle panel, inset: zoom-in of 1–1.1 μs range) and electrical spectrum (right panel) for 10-SC state. Electrical spectra show that the fundamental oscillation frequency is 69 MHz.
