Paper Abstract

We designed the Bragg reflectors and 2-D photonic crystals using the R-Soft BandSOLVE software. Following our initial designs, we fabricated the Bragg reflectors and 2-D photonic crystals on Si wafers by using two techniques, i.e. drilling holes using a UV laser and deep reactive ion etching. We then characterized the fabricated structures by measuring both the reflection and transmission spectra using the widely-tunable monochromatic THz source developed by us as well as FTIR. We analyzed and compared our results based on these two different techniques. We also investigated the dependence of the bandgaps on the fluctuation of the diameters of the air holes using the R-Soft software.
