The demand for photonics based technologies is increasing rapidly, and accurately simulating photonics in a reasonable amount of time is extremely important to design engineers. As photonics simulations are large and extremely complex, achieving high accuracy can be difficult, and photonics simulations are computationally intensive. With VSim, accuracy is obtained through time-based, full-wave 3D simulations, and simulation time can be reduced with VSim’s use of highly parallel algorithms designed for high performance computing systems.
