Coherent characterization of an integrated ring resonator based on an acousto-optic frequency-shifting loop

Caractérisation cohérente d'un résonateur intégré basée sur un boucle à décalage de fréquence acousto-optique

Résumé

Optoelectronic oscillators (OEO) are convenient devices for the optical generation of microwaves signals. In recent years OEOs have tended to be miniaturized with the integration of optical delay lines into photonics chips. Closing such integrated optical delay lines in a resonant configuration is expected to improve the OEO performances. Here we present a method for characterizing the complex transfer function of an integrated long optical ring resonator. The approach relies on an acoustooptic frequency-shifting loop that generates a dense frequency comb, enabling the retrieval of both the amplitude and phase responses of the resonator.
