The second type of simulation is related to the MZI device. For that, we use Lumerical's Interconnect. The MZI devices will incorporate circuit models for the straight and bend waveguides, and the provided S-parameter models for the Y-branch and the fiber grating couplers.  \subsection{Straight waveguide simulation results}  \subsection{Bent waveguide simulation results}  \subsection{Mach-Zehnder interferometer circuit simulation}  \subsection{Two-stage MZI optical filter circuit simulation}
