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.
