Claim 0:
1. An interferometer comprising:
a plurality of waveguide branches comprising a plurality of bus waveguides and a plurality of photonic resonators, wherein a first waveguide branch of the plurality of waveguide branches comprises:
a first photonic resonator of the plurality of photonic resonators coupled to a first bus waveguide of the plurality of bus waveguides, wherein the first photonic resonator is disposed to couple and circle a first portion of an optical beam at the first photonic resonator 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

wherein the interferometer forms at least a portion of an in-phase and quadrature (IQ) modulator.
