Claim 17:
18. A method of optical frequency shifting, comprising:
receiving an optical beam from an optical source;
directing the optical beam to a plurality of waveguide branches comprising a plurality of bus waveguides and a plurality of photonic resonators;
coupling and circling a first portion of the optical beam at a first photonic resonator of the plurality of photonic resonators coupled to a first bus waveguide of the plurality of bus waveguides to generate a first phase shift of the first portion of the optical beam, wherein the first phase shift is the same as a second phase shift of a second photonic resonator of the plurality of photonic resonators coupled to a second bus waveguide of the plurality of bus waveguides, and
forming at least a portion of an in-phase and quadrature (IQ) modulator.
