Fabrication and characteristics of polarization maintaining polymer photonic crystal fiber with elliptical core

Abstract

A novel structure of highly birefringent polarization maintaining photonic crystal fiber is designed theoretically, the fiber has an elliptical core and five ring square hexagonal structure, with the average hole-diameter, d=2.5ȝm, and the ratio of average hole-diameter and hole-spacing d/ =0.4. The polarization mode field and birefringence are numerically simulated by Beam propagation method based on full vector model. Research results showes that two orthogonal polarized states of the fundamental mode become non-degenerate in the elliptical core PCFs and appear obviously an ellipse and strongly linear polarization. Furthermore, we firstly fabricated successfully the fiber with near elliptical core based on organic macromolecule polymer material by in-situ chemical polymerization technology and the secondary draw-stretching of the preforms. The polarization mode fields and transmission loss are measured, and the results are well accorded with theory, which will be promising to fabricate high birefringence polarization maintaining photonic crystal fiber based on polymer for applications in data communication networks and for the development of range of new polymer-based polarization maintaining fibers components.
