These will be used to create a compact model in INTERCONNECT.Ĭreate a compact model in INTERCONNECT, using the optical n port s-parameter (SPAR) element and import the data from step 2.Ĭompact model generation with CML Compiler Once an optimal design is found, extract the S-parameters as a function of wavelength for each mode of interest. Transmission at the output ports is the figure of merit. This example runs sweeps over taper width and interference region length parameters. Run parameter sweeps with EME to optimize the MMI geometry. The device in this example is optimized for TE mode, but the approach can be extended to any design and polarization. The EME solver is ideally suited to characterizing these devices. Losses can be minimized by ensuring good matching between the modes of the input/output waveguides and the interference region by using linear tapers at the input/output waveguides. Low-loss optical combiners and splitters are essential components for Mach-Zehnder-based optical modulators and are key building blocks of integrated circuits. Understand the simulation workflow and key results It is also shown how to extract these parameters for compact model generation using the CML Compiler. Use the device S-parameters to create a compact model of the MMI in INTERCONNECT. Calculate the broadband transmission and optical loss through a 1×2 port multi-mode interference (MMI) coupler.
