Photonic crystals are attractive optical materials for controlling and manipulating the flow of light. One dimensional photonic crystals are already in widespread use in the form of thin-film optics with applications ranging from low and high reflect

In contrast with conventional optical fibers, photonic crystal fibers (PCF) present a diversity of new and improved features, which provide several new applications such as nonlinear fiber optics, fiber lasers, supercontinuum generation, and fibe
