In microstructured optical fibers some defects are inherent to the fabrication process. One can mention, for example, the inhomogeneity of the initial preform: diameter, position of the inclusions (when the hexagonal stack is assembled before drawing) and refractive index that evolves along its axis. These defects will lead to transverse disorders in the final fiber. Therefore, the analysis of photonic crystal fibers optical-geometric properties and their impact on transfer parameters is very important. We note that in our investigation we use finite-element method. The obtained results show that at any of considered defect types the mode field will have two pronounced maximums. The results presented in this work show that total mode field ...
