Controlling microresonator solitons with the counter-propagating pump

Abstract

Considering a bidirectionally pumped ring microresonator, we provide a concise derivation 1 of the model equations allowing us to eliminate the repetition rate terms and reduce the nonlinear 2 interaction between the counter-propagating waves to the power-dependent shifts of the resonance 3 frequencies. We present the simulation results of the soliton control by swiping the frequency 4 of the counter-propagating wave in the forward and backward directions and with the soliton-5 blockade effect either present or not. We highlight the non-reciprocity of the forward and backward 6 scans. Furthermore, we report the soliton crystals and breathers existing in the vicinity of the 7 blockade interval.
