Paper Abstract

Many of the applications of photonic crystals and photonic crystal fibers require the periodic structure to have some type of defect. In photonic crystal fibers a point defect defines the fiber core, whereas in photonic crystals a line defect acts as a waveguide, and point defects act as cavities. The modeling of these defects usually either makes use of periodic boundary conditions, by which the defect is replicated periodically, or models a photonic crystal of finite extent. However, some applications, for example the cut-off behavior of a defect mode where the field extends very widely, require methods that can model a defect in an otherwise infinite and perfectly periodic structure. Here we present such a method. It combines the method of fictitious sources with averaging over the Brillouin zone, and we apply it to study the long-wavelength behavior of the fundamental mode of photonic crystal fibers.
