Abstract:
The aim of this work is an efficient implementation of a spatially resolved current spreading model defined in the vertical-lateral domain into a dynamic electro-optical solver acting in the longitudinal-lateral plane. We introduce two numerical methods for the solution of the current spreading model and perform test simulations using different approximations of the inhomogeneous current density along the active zone.
