Abstract :
Different configurations of Bragg grating waveguides have been investigated in this paper by the finite-difference time-domain (FDTD) method. By changing the configuration of the gratings, various photonic band-gap widths can be achieved. Moreover the apodized plasmonic metal-insulator-metal (MIM) Bragg grating waveguides whose bandgaps are smoother than the same kind of simple ones are proposed, in order to suppress the side lobs.
