Abstract

Electro-optic devices for classical and quantum microwave photonics are provided. In various embodiments, a device comprises: a waveguide; a first ring resonator; a second ring resonator, the second ring resonator evanescently coupled to the first ring resonator and to the waveguide; a first pair of electrodes, one of the first pair of electrodes disposed within the first ring resonator and the other of the first pair of electrodes disposed without the first ring resonator; a second pair of electrodes, one of the second pair of electrodes disposed within the second ring resonator and the other of the second pair of electrodes disposed without the second ring resonator; a microwave source electrically coupled to the first and second pairs of electrodes; a bias port electrically coupled to the first and second pairs of electrodes and configured to sweep a frequency band.
