What's New

The 2026 R1 release of Ansys Lumerical CML Compiler introduces IBIS-AMIreduced order models, a user-friendly built-in Model Data Editor, and the ability toautomate tools with PyLumerical.

 

CML Compiler
IBIS-AMI Models

Introducing an innovative solution for generating IBIS-AMI models using machine learning. Photonic engineers can now create reduced-order models with Lumerical INTERCONNECT, enabling system designers to perform precise Signal Integrity analysis and high-speed interface simulations with confidence.

Py Lumerical
PyLumerical

Automate Lumerical tools seamlessly with PyLumerical, a Python-based solution. Fully compatible with the PyAnsys ecosystem, it integrates with FDTD, MODE, Multiphysics, INTERCONNECT, and other Ansys tools like Optislang and Speos, plus open-source Python libraries. Simplify workflows and enhance multiphysics simulations with this modern, efficient approach.

Model Data Editor
Built-in Model Data Editor

The Built-in Model Data Editor in Ansys Lumerical CML Compiler offers an interactive user-friendly interface to view and edit data directly in the GUI. It features simultaneous multi-tab editing with integrated matrix and vector editors, making it an ideal tool for handling diverse photonic models and perfect for new users starting with CML Compiler.
