Microresonators

Microresonators are micrometre-scale structures for confining light. Light is reflected internally at the edges of the resonator. This creates a series of standing-wave optical modes, or resonances, similar to those that can exist on a vibrating guitar string. Microresonators can provide the optical feedback required in semiconductor lasers.

    A turnkey regime for soliton microcombs is demonstrated, in which solitons are generated by switching on a co-integrated pump laser, eliminating the need for photonic and electronic control circuitry.

    Here, the authors demonstrate acousto-optic modulation of silicon nitride microring resonators using high-overtone bulk acoustic wave resonances, allowing modulation in the GHz range via acoustic waves. As an application, an optical isolator is demonstrated with 17 dB non-reciprocity.
