What's New
The 2023 R2 release introduces new FDTD simulation performance acceleration using a single GPU, new features for advanced CMOS image sensor design, and enhanced flexibility for defining geometries using the layer builder feature.
GPU Acceleration
GPU enables faster FDTD simulations with parallelization on the graphic card. A single GPU Nvidia RTX4000 can offer a 6x speedup. This first version of GPU-supported FDTD runs on a constrained set of resources, monitors, and materials behaviors compatible with a single GPU.
New Layer Builder Boolean Operations
This new feature in Lumerical Multiphysics Suite supports operations between any mask layers. Enables cases where a combination of multiple mask layers determines the geometry.
CMOS Image Sensor Workflow Enhancements
FDTD includes the marginal rays from OpticStudio in the pixel simulation for an accurate calculation of the quantum efficiency. The EQE vs. subpixel position and wavelength is combined with Speos light exposure and post-processed by the new Speos sensor system to see all intermediate and final electronic images.
