Effective index of mode
WebJun 17, 2024 · How do you find the effective index of a waveguide? the effective mode index can be computed by a simple equation in which we divide propagation constant over the wave number. (Neff = B/k0, B= propagation constant and K0= wave number). is there any way except this formula to calculate effective mode index? can any one explain … WebThe mode_info object contains information about the effective index of the mode and the field profiles, as well as the mode_spec that was used in the solver. The effective index data and the field profile data is in the form of xarray DataArrays. We can for example plot the real part of the effective index for all three modes as follows.

Hi, I tried our example model step_index_fiber_bend and you should get the effective mode index (at radius r0) with the expression "ewfd2.neff/r0". This evaluates to about 1.4435-2.052e-6i, so the imaginary part is pretty small and by default COMSOL is only displaying the real part.
