High- Q microresonators are indispensable components of photonic integrated circuits and offer several useful operational modes. However, these modes cannot be reconfigured after fabrication because they fixed by the resonator’s physical geometry. In this work, we propose a Moiré speedup dispersion tuning method that enables microresonator device to operate in any three Electrical Vernier coupled rings switches operating modality Brillouin laser, bright microcomb, dark microcomb operation on demand using same hybrid-integrated device. phase matching across telecom C-band is demonstrated. Likewise, single-pump wavelength, mode can switched. As result, one universal design applied range applications. The brings flexible mixed-mode circuits.
