Linear photonic frequency discriminator on As₂S₃-ring-on-Ti:LiNbO₃ hybrid platform. Academic Article uri icon

abstract

  • We report a photonic frequency discriminator built on the vertically integrated AsS-ring-on-Ti:LiNbO hybrid platform. The discriminator consists of a Mach Zehnder interferometer (MZI) formed by the optical path length difference (OPD) between polarization modes of Ti-diffused waveguide on LiNbO substrate and a vertically integrated AsS race-track ring resonator on top of the substrate. The figures of merit of the device, enhancement of the signal-to-3rd order intermodulation distortion (IMD3) power ratio and corresponding 3rd order intercept point (IP3) over a traditional MZI, are demonstrated through device characterization.
