Waveguiding properties of a photonic crystal fiber with a solid core surrounded by four large air holes

Opt Express. 2009 Apr 27;17(9):6931-8. doi: 10.1364/oe.17.006931.

Abstract

The polarization-dependent guiding properties of a hexagonal-lattice photonic crystal fiber with a solid-core surrounded by four large air holes are investigated. The appearance of a polarization dependent cutoff frequency, together with several parameters as the birefringence, the modal effective area, the group velocity dispersion and the polarization dependent loss are analyzed. A collection of fibers with different structural parameters were fabricated and characterized. An effective anti-guide structure from at least 450 nm to 1750 nm, a polarizing fiber with a polarization dependent loss of 16 dB/m at 1550 nm, and an endlessly singlemode polarization-maintaining fiber with group birefringence of 2.1x10(-3) at 1550 nm are reported. Experimental results are compared with accurate numerical modeling of the fibers.
