В работе представлена модификация метода линий для расчета параметров направляемых мод прямых и изогнутых микроструктурированных волокон с тремя сердцевинами. Проанализированы эффективные показатели преломления, коэффициент потерь на излучение, а также поперечное распределение полей основных мод таких волокон в зависимости от их структурных параметров (диаметра и разнесения воздушных отверстий, разнесения сердцевин) и величины изгиба. 

We present the modification of the line method for calculation of the parameters of guided modes of straight and bent three-core microstructured fibers. On the basis of the method proposed, we analyzed the effective indices, radiation loss coefficients and a transverse field distribution of the fundamental modes in such fibers as a function of their structure (air holes diameter and separation, core separation) and bend value.
