Abstract

In this work, a novel design of dielectric zero-index metamaterial (ZIM) filled photonic crystal defect waveguides have been proposed. The ZIM used here is basically a photonic crystal having Dirac cone at gamma point of the band structure. Existence of Dirac cone implies the linear dispersion in the vicinity of the Dirac point which is the main reason behind the zero-index behaviour. It has been shown in this article, that when such metamaterial is inserted inside a photonic crystal defect waveguide it reduces the effect of bending on transmission coefficient as compared to the conventional designs. The proposed design comprises of square arrays of Si rods in air, in which, the periodicity to wavelength ratio (a/λ) for ZIM and the surrounding photonic bandgap (PBG) structure are 0.541 and 0.35 respectively. Wavelength of operation is 1550 nm. Furthermore, as the ZIM is made up dielectric only, its free from ohmic losses.
