Semiconductor-Electromagnetic Waves Coupling
The Semiconductor-Electromagnetic Waves Coupling () node passes the optical field intensity from an electromagnetic waves interface to the Optical Transitions feature in the Semiconductor interface. The change in the complex refractive index or permittivity that results from the absorption in the semiconductor is then passed back to the electromagnetic waves interface.
Settings
The Label is the default multiphysics coupling feature name.
The Name is used primarily as a scope prefix for variables defined by the coupling node. The software refer to variables in expressions using the pattern <name>.<variable_name>. In order to distinguish between variables belonging to different coupling nodes or physics interfaces, the name string must be unique. Only letters, numbers, and underscores (_) are permitted in the Name field. The first character must be a letter.
The default Name (for the first multiphysics coupling feature in the model) is semc1.
Domain Selection
The default setting is All domains which couples all domains in the Semiconductor interface that have an active Optical Transitions feature with the corresponding domains in the electromagnetic waves interface.
Coupled Interfaces
This section defines the physics involved in the coupling. By default, the software selects an appropriate physics interface for you from the Semiconductor and Electromagnetic waves lists. These selections determine the two interfaces that are coupled by the feature.
