Abstract

In this paper, a nano-dots one-dimensional (1-D) photonic bandgap (PBG) filter design based on SOI waveguide is presented. The air dots in the polymer rod with various radii are compared in this paper. The simulation technique of the light propagates in our designed 1-D PBG waveguides is using the beam propagation method (BPM). The 1-D SOI PBG geometry we investigated consists of a three-layered dielectric structure. We assume various wavelengths at 1.3 μm and 1.5 μm windows are launched to the 1-D PBG SOI filter waveguide to see the simulation results. The air nano-dot wavelength selection effect is demonstrated. The output spectrum adjustment with nano-dots in 1-D PBG filter is dependent on the size of these PBG rods.
