How to extract the phase information from the simulated data on COMSOL

Please login with a confirmed email address before reporting spam

On wave optics module of COMSOL, I have been attempting to simulate the Distribute Bragg reflector (DBR) structure. After developing the model, I plotted the reflection spectrum while altering the wavelength and obtained the correct result. Now I would like to create a phase  vs. wavelength graph for the same structure. I have attached a diagram to illustrate what I am looking for. I already obtained the blue graph in the figure; now I want to obtain the red one. Could someone please explain me how I can do this?

The phase of a phasor quantity A is atan2(Im(A),Re(A)).

The phase of a phasor quantity A is atan2(Im(A),Re(A)).
