We used COMSOL Multiphysics® software to calculate the mode distribution by numerically solving the wave equation in the fiber. We consider the transmission from the fiber 1 to the fiber 2. In the first case, the transmission was calculated as function of the wavelength of the propagated mode. We observed that the transmission for the fundamental mode on fiber 2 has a maximum at the same wavelength where the transmission for the first excited mode has a minimum. In the second case, the transmission was calculated as function of the transversal misalignment between the two fibers. Excited modes have its maximum with a nonzero misalignment, when the second fiber is dislocated from the first one.
