The excess loss that occurs in waveguide bend can be minimized by offsetting the connecting waveguide so as to reduce the transition loss at the junctions. Such bends were investigated in detail by employing the BPM(Beam Propagation Method) and it was found that they can be optimized with respect to overall loss In the addition, S-shaped waveguides and directional couplers with offset junctions were simulated by BPM
