FDTD and MODE now supports inclusion of process variations in process files. This enables users to run Monte Carlo sweeps in their design stage to automatically perturb the device geometry using the information from the process file to ensure the robustness of their design against process variations.
The RCWA solver is now fully released with additional enhancements that will allow the users to collect electric and magnetic field data at selected planes. The solver performance has also been enhanced with a minimum of 10-20% increase in simulation speed.
The CHARGE solver has a new ‘quality mesh constraint’ object that can be used to control the mesh quality on a user defined volume within the simulation region. The ‘mesh’ settings in CHARGE also have a new option named ‘disable interface mesh autorefinement’ to disable the automatic mesh refinement at interfaces between different partitioned domains. These two options can be used to avoid oversampling the mesh in, for example, high aspect ratio domains where the thickness is much smaller than the area and enable faster simulation.
The stackrt script command now supports fully anisotropic and dispersive materials by specifying the refractive index of each layer as a second-order tensor (3x3 matrix).
The FEEM solver now reports additional mode properties including TE polarization fraction, waveguide TE/TM fraction, and effective area for the calculated modes.
The EME solver in MODE reports additional diagnostics that capture the power associated with forward- and backward-propagating coefficients, as well as the cross-coupling between the two directions.
SYSTEM Suite Enhancements
Starting from the 2022 R1.2 release, the KLayout - INTERCONNECT integration package is included in the Lumerical installer.
This bundled option is currently available in the Windows installer only and will be available in the Linux installer in an upcoming release.
