The numerical code was developed for calculation of the fiber modes in the active core assembly. The shift‐and‐invert Arnoldi method was used for such a problem. We have developed the propagation code realizing the second‐order implicit finite difference scheme, which incorporates the perfect‐matched layer boundary conditions at the computational region boundary. Our eigenvalue problem solver and propagation code were tested by comparison with analytical solutions for a single‐core fiber. The results of simulations of fiber structure with 2 evanescently coupled cores are presented.
