Calculating adjoint sensitivity



I want to do a parameter optimization for which I need to know the sensitivity of the parameter. Does Lumerical have an option to calculate adjoint sensitivities of parameters?



Hi @audupa2

The built in parameter optimization is based on particle swarm optimization.:

I am not familiar with the technique, but you can probably run the simulations and calculate the quantity of interest in a post processing step. If you are interested in using other optimization algorithms, you can also use Python API (requires license) to control your simulations and calculate the adjoint sensitivity:

Hope I could answer your inquiry.
