Slow and Fast Axis calculation based on bending radius

    • Nathan Lin

      I have a waveguide with a refractive index of 1.45, and the slow axis is in the x-axis and the fast axis is in the y-axis. When we apply the bending radius using FDE, the slow and fast axis shifts a few degrees accordingly as shown in the refractive index shift graph below, is there a way to set the principle (slow-axis) in the simulation?

      You can run the frequency sweep by selecting TE polarization.

      If thats not answed the question, can you elaboate a little more.
