Zero birefringence 8-fold photonic quasicrystal (QC) fiber

Abstract

In this work we present numerical results of a new class of index guiding photonic crystal fibers achieved with a quasicrystal (QC) lattice structure. The fiber is composed of pure silica 8-fold lattice cladding where few missing holes represent the core region. Our numerical results demonstrate that the proposed QC photonic fiber presents a wide single mode regime. On the other hand, due to its symmetry, the 8-fold structure shows a very close to zero birefringence value. © 2014 IEEE
