Capabilities

Easily handle the complexity of varied design environments with a range of analytical tools that enable you to meet performance goals and ensure long-term reliability.

Ansys Lumerical FDTD solver is the flagship of Lumerical. It’s an optimized solver based on the Finite-Difference Time-Domain simulating the light propagation in photonic structures at nanoscale.

It has high accuracy with options for auto non-uniform meshes. Lumerical FDTD is also foundry compatible and supports automated design processes with its scripting capabilities, advanced post-processing, and optimization routines.

Based on the Rigorous Coupled Wave Analysis method, Lumerical RCWA complements Lumerical FDTD and STACK by rapidly simulating light scattering for periodic and multilayer structures.

RCWA provides fast simulations of complex multilayer stacks with surface patterning, from capturing the electric and magnetic field distributions to transmitting, reflecting, and evaluating power in each grating order.

The STACK Analytic solver is faster than the direct simulation of Maxwell’s equations. It is ideal for rapid prototyping for thin film applications. From capturing microcavity effects and interference to handling dipole illumination and plane wave functions, STACK provides quick simulations of complex thin film multilayer stacks.

Automatically discover optimal designs and geometries for a targeted figure of merit.

Discover non-intuitive geometries that optimize performance, minimize area, and improve manufacturability.

Powerful post-processing capability, including far-field projection, band structure analysis, bidirectional scattering distribution function (BSDF) generation, Q-factor analysis, and charge generation rate.

Simulate devices fabricated with nonlinear materials or materials with spatially varying anisotropy.

Choose from various nonlinear, negative index, and gain models. Define new material models with flexible material plug-ins.

Use multi-coefficient models for accurate material modeling over large wavelength ranges.

Automatically generate models from sample data or define the functions yourself.

The integrated design environment provides scripting capability, advanced post-processing, and optimization methods.

FDTD’s CAD environment and parameterizable simulation objects allow rapid model iterations for 2D and 3D models. It provides eye comfort with Dark Mode and is fully compatible with 4k high DPI screens and modern 3D views.

Create 3D multi-layered structures from planar unpatterned layers and patterns imported from a GDS file.

Change the position, ordering, and thickness of each layer. Simulate curved side-angled waveguides, then export the layer configuration, including material data, as a process file (.lbr) that foundries can fabricate.​

Advanced Photonic Simulation Workflow with state-of-the-art algorithms for design exploration, optimization, robustness, and reliability analysis

Automate multiphysics simulation workflows and benefit from the state-of-the-art sensitivity analysis and optimization algorithms available in optiSLang.

Lumerical is part of Ansys Optics, providing interoperability solutions and design workflows with OpticStudio and Speos.

The Lumerical Sub-Wavelength Model (LSWM) plugin allows you to simulate and design coatings, polarizers, and diffraction gratings in OpticStudio and Speos.

Smart Strategies for Large Structural Simulations

One way to gauge the progress of engineering simulation software is through the lens of size. Engineers today routinely run structural simulations with a few million degrees of freedom, and the largest commercial structural simulations have topped even 100 million degrees of freedom.
