Backscattering-induced oscillated breathing soliton microcomb
Abstract
The interplay between Rayleigh backscatter and Kerr nonlinearity has attracted intensive interest. However, strong Rayleigh backscatter, accompanied by mode-splitting, has a negative impact on the formation of soliton microcombs. Here, we propose a local dispersion method to enable the formation of a breathing soliton in the mode-splitting microcavity, demonstrating the energy exchange process between the counter-propagating waves. Besides, we also note that, via locking the oscillated frequency, the repetition rate of the breathing soliton microcomb could be enhanced. Our work paves the way for exploring the soliton dynamics and provides a novel, to the best of our knowledge, method to lock the soliton microcomb.
