| Abstract: | A bent waveguide is an indispensable element in planar photonics waveguide devices.It is a key task to simulate the field propagating in bent waveguides.In this paper simulations for bent waveguides have been carried out with wide angle BPM at polar coordinate system.And results are compared with those using other methods. |
