Periodical dielectric waveguide (PDWG); Finite-difference time-domain (FDTD) method
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 90transitional 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.
