Abstract
Example optical devices having a Mach-Zehnder interferometer (MZI) with improved linearity are presented. An example optical device may include an MZI and a microring resonator (MRR) optically coupled to any one of a first optical waveguide arm or a second optical waveguide arm, where the MRR is operable in a resonance state and in an off-resonance state during operation of the optical device. The MZI includes a length difference between the first optical waveguide arm and the second optical waveguide arm thereby achieving a quarter-period phase delay between optical signals of the first optical waveguide arm and the second optical waveguide arm such that a superlinear transmission region of the microring resonator is aligned with peaks of an optical output of the MZI improving linearity of the optical output of the MZI.
