Built on the finite element drift-diffusion method, CHARGE provides designers with the correct tools for comprehensive charge transport simulation in active optoelectronic and photonic semiconductor devices.
Improve your charge transport simulations across a range of applications
Lumerical CHARGE provides designers with the tools for comprehensive charge transport simulation in active photonic and optoelectronic semiconductor devices. CHARGE self-consistently solves the system of equations describing electrostatic potential (Poisson’s equations) and density of free carriers (drift-diffusion equations). Automatic and guided mesh refinement tools are provided to achieve accuracy while minimizing computational effort.
Lumerical CHARGE provides complete simulation and modeling solution so you can focus on ideas and products. A range of features create flexible solutions for 3D charge transport, simulating across a mixture of material properties and a wide range of application types.
JULY 2023
The 2023 R2 release enables auto-generation of geometries via our Layer Builder capability, easier workflows to sync the design of devices in Lumerical with Layouts in Cadence Virtuoso, and high-speed Lithium Niobate electro-optic modulators.
A new feature in Lumerical Multiphysics Suite supports operations between any mask layers. This feature enables cases where a combination of multiple mask layers determines the geometry
The DC relative dielectric permittivity definition for electrical materials in CHARGE now supports diagonal anisotropy, enabling accurate modeling of thin-film Lithium Niobate electro-optic modulators.
The wizard enables optimization of active devices using Lumerical Photonic Multiphysics Suite of solvers (CHARGE, HEAT, FEEM) together with Cadence Virtuoso for the layout.
