摘要: We theoretically investigate waveguide bends in three-dimensional dielectric photonic bandgap (PBG) materials. The PBG materials used this study consist of layers alumina rods. An L-shaped is created by removing part the rod one layer and next layer. removed rods are perpendicular to each other. Using finite-difference time-domain (FDTD) simulations, we found that 100% transmission efficiency can be achieved through 90° bend. ©1999 John Wiley & Sons, Inc.
