摘要

High-Qmicroresonators are indispensable components of photonic integrated circuits and offerseveral useful operational modes. However, these modes cannot be reconfigured after fabricationbecause they are fixed by the resonator's physical geometry. In this work, we propose a Moir & eacute; speedupdispersion tuning method that enables a microresonator device to operate in any of three modes.Electrical tuning of Vernier coupled rings switches operating modality to Brillouin laser, brightmicrocomb, and dark microcomb operation on demand using the same hybrid-integrated device. Brillouinphase matching and microcomb operation across the telecom C-band is demonstrated. Likewise, byusing a single-pump wavelength, the operating mode can be switched. As a result, one universal designcan be applied across a range of applications. The device brings flexible mixed-mode operation tointegrated photonic circuits
