Ansys Lumerical’s Component Level Tools

This webinar will start with an overview of the broad set of component level solvers it offers with an emphasis on FDTD and MODE. It will then show how these solvers can be used to simulate and optimize novel designs in a wide range of applications including micro-LEDs, augmented reality, magneto-optics and lasers.
