摘要：

In this paper a Simple low-loss planar waveguide wide-angle bend is proposed and analyzed. The waveguide bend of this work consists Of a Curved tapered angle such that its tapering can be adjusted for a minimum loss (maximum transmission coefficient) and small dimension of bend. The analysis is done using wide-angle BPM (beam propagation method) type Pade (4,4). The simulated results of different bends show that at the same transmission coefficient the area required for the proposed bends are smaller than those of the abrupt bends. (C) 2007 Elsevier Ltd.
