Abstract

Study of Dispersion in Elliptical Core Photonic Crystal FiberPhotonic crystal fibers (PCF)have attracted increasing interest over the past few years because of their ability to provide manipulation in optical properties of light. High birefringence can be easily achieved in PCFs based on design flexibility and the large index contrast. Amongst several designs high birefringence exceeding 10-3 has been shown. Birefringence of the PCF can be further improved by employing elliptical air holes in the fiber cladding and also by using certain material such as coumarin in place of air. In this paper an ultrahigh birefringent PCF with ultra low confinement loss is proposed by employing elliptical holes in the fiber core to induce the birefringence but circular air holes in the fiber cladding to reduce the confinement loss. Such a design is able to offer is able to offer a perfect solution to the tradeoff between the high birefringence and the confinement loss in elliptical-hole PCFs. MATLAB and COMSOL softwares has been used for the coding and simulation. The results provide a method for reducing confinement loss and suggest an approach for modify the effective index of the fiber core which is used for getting zero dispersion.
