We recently introduced a user interface for the STACK script commands. These are powerful and efficient tools for understanding plane wave transmission/reflection and dipole emission/efficiency for 1D structures.
These features can be previewed in this Spark Video. For anyone interested in working with these tools I have built a a couple models that you may modify and readily test.
BraggReflector.fsp (277.8 KB)
Simple quarter wave Bragg reflector. Look at angualr dependent RT values.
VCESEL.fsp (300.1 KB)
Model of a vertical-external-cavity surface-emitting-laser with dipole placed in the cavity.
