which software is most suitable for LED simulations

[Guilin Sun]

If the LED is thin layer structure without nano structure, using stack functions are easier, faster and more accurate without discretization error:
STACK Optical Solver Overview ÔÇô Lumerical Support
stackpurcell - Script command ÔÇô Lumerical Support
stackdipole
Stack dipole half-space
Example can be found here Micro-LED ÔÇô Lumerical Support

If there is nano structure, FDTD simulation must be used. OLED examples can be references:

Is there any complete tutorial available for STACK solver? how to take the results reflectivity and transmission of a stack.
