Photonic band gaps of two-dimensional complex periodic photonic crystals

Huang Xiao-qin

Abstract

A two-dimensional complex periodic photonic crystal structured by hexagonal lattice and triangular lattice is presented.Using the plane-wave method,we have calculated the photonic band structure of this complex periodic photonic crystal consisting of dielectric rods of circular cross section.It is shown that this structure reveals many wide photonic band gaps for TE modes and exists an absolute photonic band gap for both TE and TM modes.
