Iwant to simulate a fiber modulator in lumerical mode solution by eigensolver but the results depend on simulation region size. what is the simulation region size at metal boundary condition in lumerical mode solution?
furthermore after eigenmode analysis in mode solution, i can't recognize te and tm mode in mode list. is the first te mode and the second tm?
i would be very grateful if someone answer my two questions.

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?
