Quasi-Single-Mode Fibers with Increased Core Size Based on Non-Hexagonal Type Microstructures

Abstract
The capabilities of silica-based microstructures with a large (40 μm in diameter) core and a nonhexagonal (circular) distribution of voids in the cladding for enhancement of the fundamental (LP01) mode confinement under bent condition are analyzed numerically. It has been determined that the criterion for obtaining a single-mode propagation in such optical elements is a high level of attenuation for the polarization component HE21 of the higher-order mode LP11.
