Using INTERCONNECT model in OptoCompiler: CML Compiler generates OptoCompiler library containing component symbols and INTERCONNECT-ready compact models. You can either set it via the CML Compiler GUI or its library JSON file.
Proxy support for connected services: All proxy settings for Lumerical are now consolidated in the License.ini preference file. These proxy settings apply globally to all connected services, including licensing, Ansys Engineering Copilot, and Ansys Cloud Burst Compute™ for Lumerical. Previous settings in product-specific preference files are automatically migrated.
Ansys Lumerical FDTD™
GPU Improvements:
Np density grid attribute in FDTD GPU: FDTD GPU now supports np density attribute objects. This enables you to use GPU to simulate active devices requiring index perturbation from charge densities.
Warning for stale result files: A warning now shows when GPU result files are stale. This helps with cases such as when network issues disrupt the download when running simulations with Ansys Burst Compute™.
Lumerical inverse design module lumopt2:
Symmetry boundary conditions support: The lumopt2 inverse design module now supports symmetry boundary conditions, providing another method to enforce symmetrical geometry, and minimizing memory usage for symmetrical devices.
Support for auto rotation with zbf2 files: The script commands zbf2read and zbf2write now supports auto rotation matrices, which helps with translating the electric field from reference coordinates to zbf2 coordinates.
Ansys Lumerical Multiphysics™
Improved convergence of high-field mobility models: Two new driving fields, “E” and “E dot J approx,” are now available in the high-field mobility model in Semiconductor materials. Compared to the existing driving fields, “E dot J” and “grad phi,” these new driving fields have improved solver convergence properties resulting in high simulation success rate in CHARGE solver for simulations such as the bandwidth of photodetectors and modulators. For more details, see the description of driving fields in the high field mobility models at Semiconductor Material Model Properties. The following application gallery examples have also been updated:
The Vertical photodetector example now includes the comparison of the bandwidth simulation results with different driving fields for the high field mobility.
The Avalanche photodetector example now has a new section for the bandwidth simulation as well as comparison of different driving fields.
Non-linear ring modulator model: The Kerr non-linearity effect is added to the Nonlinear Ring Modulator model in INTERCONNECT. This enables you to more effectively model high-Q rings to accurately predict dynamic processes such as self-pulsation.
Self-heating for multi-section TWLM: The traveling wave laser model (TWLM) in INTERCONNECT now supports self-heating effects across multiple sections, enabling you to account for these effects in devices such as partially corrugated DFB lasers.
Ansys Lumerical CML-Compiler™
GF 10-70 PDK Support: The Verilog-A models generated from CML-Compiler now supports interoperability with models included in the GF 10-70 PDK.
