What's New

The 2023 R2 release of Ansys Lumerical introduces a series of powerful new capabilities to extend usability, accuracy, performance, and functionality across its family of products. Here are a few new capabilities in our 2023 R2 release:

  • Ansys Lumerical CML Compiler further simplifies the process of compact model generation via its new CML Compiler GUI featuring intuitive controls and menu options
  • Ansys Lumerical Multiphysics Suite & Cadence EPDA flow enables optimization of the layout and performance of photonic components via the new Geometry Wizard
  • Ansys Lumerical FDTD accelerates design cycles by enabling GPU-powered simulations, especially for photonic integrated component design and metasurface applications. A single GPU Nvidia RTX4000 can offer a 6x speedup versus a 12-Core CPU 
  • Ansys Lumerical streamlines workflows and facilitates remote job execution with the new remote Python API
  • Ansys Optics Launcher and its intuitive in-product experience enable fast access to all Ansys Optics product trials and application gallery example files from any of the Ansys Lumerical, Ansys Zemax, or Ansys Speos products
  • Ansys Lumerical RCWA enables advanced simulation and analysis by new field monitors, oriented meshing, interface position autodetection, and distributed sweeps. It's advantageous for diffraction gratings, metalenses, optical metrology, holography, metamaterials, and IR sensors
  • Ansys Lumerical FDTD and RCWA enable designs of larger metalenses up to 25 mm in diameter and speeds up their simulation by 10-100 times using faster workflows with more intelligent memory management, new features in RCWA GUI, GPU-powered FDTD, and faster GDS file export capabilities 
  • Ansys Lumerical FDTD, CHARGE, Ansys Zemax OpticStudio, and Ansys Speos have increased the accuracy and range of analysis for a complete end-to-end Camera Image Sensor virtual prototyping solution. Ansys FDTD enables accurate quantum efficiency (EQE) calculations by including the marginal rays from OpticStudio in the camera pixel simulations
  • Ansys Lumerical qINTERCONNECT brings performance improvements by allowing double the number of channels or frequencies with the same simulation run time, especially useful for achieving higher frequency resolution of the biphoton wavefunction for HOM measurement
  • Ansys Lumerical INTERCONNECT now enables the modeling of nonlinear LiNbO3 waveguides by supporting second harmonic generation, both short pulse and CW pump operations, and tuning with periodic polling

Ansys Lumerical's photonics simulation and design capabilities enable engineers to model nanophotonics devices, circuits, processes, and materials.

  • Circuit-level Simulation
  • Nanophotonic Component-Level Simulation
  • 3D CAD Environment with Post-Processing Capabilities
  • PDK Workflows
  • Automation and Scripting Support
  • Laser Workflows
  • Photonic Inverse Design with lumopt
  • Compact Model Generation

Our solutions work together seamlessly so you can model the most challenging problems in photonics. Flexible interoperability between tools enables a variety of workflows that combine device multiphysics and system-level photonic circuit simulation with third-party design automation and productivity tools. 

A finely tuned implementation of the FDTD method delivers reliable, powerful and scalable solver performance over a broad spectrum of applications. The integrated design environment provides scripting capability, advanced post-processing and optimization routines, all allowing you to focus on your design. 

3D CAD environments with parameterizable simulation objects allow for rapid model iterations. Build 2D and 3D models, define custom surfaces and volumes and import geometry from standard CAD and IC layout formats. 

Ansys’ photonic integrated circuit (PIC) simulation tools work in conjunction with industry-leading electronic design automation (EDA) simulators to facilitate the design and implementation of electronic–photonic integrated systems. Electronic–photonic design automation (EPDA) workflows are available with Virtuoso® and Siemens EDA.

Build, run, and control simulations across multiple Lumerical tools, or interface with third-party applications. Leverage Lumerical scripting language, Matlab, or Python to make use of numerical analysis, visualization, optimization, and more.

Lumerical offers an integrated set of tools to model many common edge-emitting laser topologies. The hybrid modeling approach combines the accuracy of physical simulation with the performance and scale of photonic integrated circuit simulation. Design and model everything from SOAs and standalone FP and DFB lasers to complex external cavity DBR and ring or sampled grating Vernier lasers.

Automatically discover optimal geometries for a desired target performance and discover non-intuitive geometries to optimize performance, minimize area and improve manufacturability. Use shape-based or topology optimization and simulate performance to find the best solution.

Proven, automated, cross-simulator photonic compact model library (CML) generation. CML Compiler automates the creation, maintenance and QA testing of INTERCONNECT and Verilog-A photonic compact model libraries (CMLs) from a single data source of characterization measurements and 3D simulation results.

Process-enabled custom design flows that empower designers to quickly augment existing PDKs with custom passive and active components that adhere to foundry specifications. 

Integration with Ansys Speos bridges the disconnect between nanophotonic simulation and macroscale simulation of the environment allowing designers to consider the effects of illumination, viewing angle, and human perception.

Demonstration workflows are available for display and image-sensor applications.

OptiSLang can drive Lumerical products in complex workflows, allowing designers to benefit from its design optimization and sensitivity analysis capabilities.

Demonstration workflows are available for display and modulator applications.

Efficiently create photonic compact model libraries (CMLs) for use in photonic process design kits (PDKs). Use CML Compiler for the creation, maintenance, and quality assurance (QA) testing of INTERCONNECT and Verilog-A photonic CMLs.
