GDSII export: A new script command, gdsaddstencil, has been introduced to convert geometries in Lumerical into polygon elements in a GDS cell. This new command supports larger and more complex geometries compared to previous GDS commands, simplifying the GDS export workflow.
Lumerical for Ansys Access / Ansys Gateway: The full Lumerical 2025 R2 software is now available on Ansys Access and Ansys Gateway.
Layer builder: The Python script used to generates the .lbr process file from the input .csv files now includes a quality assurance (QA) step. This step ensures consistency between the .lbr file tent with the .csv files issuing a warning if discrepancies are detected.
Ansys Lumerical FDTDTM
Ansys Cloud Burst Compute™ for Ansys Lumerical FDTD™ :
Submit and Forget: This new feature allows users to submit jobs to Ansys Cloud Burst Compute without the need to keep the Lumerical FDTD desktop application open. Users can now submit jobs, close the desktop application, and later retrieve results from the Ansys Engineering Portal.
S-Parameter Sweeps: Users can now perform S-parameter sweeps similarly to parameter sweeps, providing more flexibility and efficiency in simulation workflows.
GPU Acceleration Enhancements:
Multi-Node Multi-GPU Time Monitors: Time monitors are now fully supported in Multi-Node Multi-GPU FDTD simulations, matching capabilities of Single-Node Multi-GPU FDTD simulations.
Volumetric Current Source: The volumetric current source, which is a part of the field region object used with the lumopt photonics inverse design library, now supports GPU simulations.
RCWA Solver Enhancements:
Field monitors for Anisotropic Materials: The RCWA solver now supports field monitors and can report field amplitudes and grating characterizations in simulations with fully anisotropic materials.
Ansys Lumerical INTERCONNECTTM
Non-Linear Ring Modulator Model: A new Non-Linear Ring Modulator element has been added to Lumerical INTERCONNECT. Based on the existing Ring Modulator, this new compact model incorporates nonlinear behaviors arising from free carriers and self-heating effects. This model offers more accurate simulation of silicon microring modulators.
