Photonic Band Gaps of the Honeycomb Photonic Crystal Fiber Structure

In this study, full wave solutions are presented for a photonic crystal fiber structure with cylindrical air holes of circular cross-section in a honeycomb type periodic arrangement on silica substrate, and a low index core region obtained by introducing an extra air hole. Numerical results are presented for the variations of the band structure and modal fields which are obtained via plane wave and localized basis function expansion techniques, respectively.
