Abstract

We report the impact of the pattern layout on the performance of Fano broadband reflectors based on 2D photonic crystals (PCs) on silicon-on-insulator. Two representative PC patterns including hexagonal and square are fairly compared with same buried oxide (BOX) layer thickness and equivalent refractive index of silicon layer by using 3D FDTD technique. Both red- and blue- spectral shifts are demonstrated with either addition of oxide on top, and/or selective etching of the BOX below. The hexagonal pattern can offer larger bandwidth with a bit lower reflectance as compared to square one. Additionally, it is more sensitive to etching thickness.
