In this work we demonstrate a dual-comb configuration in a single crystalline microresonator by monochromatically pumping counter-propagating solitons in the same spatial mode with equal powers. Moreover, we demonstrate experimentally and through simulations the key role of Cherenkov radiation interferences on the repetition rate of a multi-soliton state. This result not only shines new light on the impact of dispersive waves on dissipative Kerr solitons but also introduces a novel approach to develop coherent dual-comb spectrometer based on microcombs.Engineering, Electrical & ElectronicOpticsPhysics, AppliedEngineeringPhysicskerr frequency combsdual-combmicroresonatorssolitondispersive wavefrequency stabilizationsolitonsDual comb generation in a monochromatically driven crystalline microresonatortext::conference output::conference proceedings::conference paper
