موجبرهای نواری سیلیکونی پیاده سازی شده برروی عایق با توری براگ یکنواخت وتوری اپودایزشده

In this paper, we have proposed silicon-on-insulator (SOI) strip waveguides with sidewallcorrugated uniform and apodized Bragg gratings. It has been shown that the rectangularcorrugations are displayed wider bandwidth compared to the sinusoidal ones. By varying thegrating parameters, the bandwidth of the waveguide with uniform gratings can be modified inorder to achieve good filtering characteristics. We have also investigated the effect of threeapodization profiles on suppressing the side lobes of the transmission and reflection spectra. It hasbeen deduced that among all inspected apodizations, Blackman profile shows the best performance and lessens the side lobes as low as -40.5 dB.
