Abstract

This paper presents the results of the finite element modeling of a unique 6-rod bundled sapphire photonic crystal fiber. The structure is composed of five rods of single crystal sapphire fiber 70μm in diameter symmetrically arranged around a solid single crystal sapphire core region, which is 50μm in diameter. The modeling work focuses on the optimization and modal analysis of this photonic crystal fiber using Comsol Multiphysics 4.2a. In sensor design and realization, reduction of the modal volume of the fiber can offer significant advantages, and as such, this research work is focused on computational determination of the structures, which may minimize the number of modes of the sapphire photonic crystal fiber. The fiber design being analyzed in this paper may be especially important for sensors operating in harsh high temperature environments.
