Capabilities

Key Features

FDTD 3D Electromagnetic Solver

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.

RCWA Solver

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.

STACK Solver

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.

Photonic Inverse Design

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

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

Post-processing Analysis

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

Nonlinearity and Anisotropy

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.

Material Multi-coefficient Models

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

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

3D CAD Environment

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.

Layer Builder

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.
