WebNext, we can check the "bent waveguide" option, and calculate the mode in the bent section of the waveguide. For this example, the bent radius is chosen to be 1.5 um and since the bend is in the same plane as the straight section, the orientation angle is zero. The propagation loss of this mode in this case is about 0.0009 dB/um.
