Abstract :
The electric field distribution and loss in a single-mode bent slab waveguide are analysed by the beam propagation method. The steady-state results obtained at large axial propagation distances are compared with other theoretical results. Reduction in bending loss is demonstrated by introducing a trench section which is placed on the outer side of the bend.
