Band-gap Engineering and Defect Modes in Photonic Crystals with Rotated Hexagonal Holes

Matthews, Aaron; Mingaleev, Sergei F; Kivshar, Yuri

Description

We study the band-gap structure of two-dimensional photonic crystals created by a triangular lattice of rotated hexagonal holes and explore the effects of the reduced symmetry in the unit-cell geometry on the value of the absolute band gap and the frequencies of localized defect modes. We reveal that a maximum absolute band gap for this structure is achieved for an intermediate rotation angle of the holes. This angle depends on the radius of the holes and the refractive index of the background...[Show more]
