The transmission characteristics of various bent periodical dielectric waveguides (PDWGs) are analyzed by the finite-difference time-domain (FDTD) method in this work. The bending structures include a conventional 90° abrupt bend, a 90° transitional bend, and 90° circular arcs with different quantized radii of curvatures. The simulation results can make us to design a suitable bent PDWG in the photonic circuits.
