Abstract :
The point-matching technique on boundary conditions is applied to the modal analysis by extending the method in a previous paper by the authors (ibid., vol.LT-4, p.991-6, 1986). The coupling-field characteristics of the optical fibers are then analyzed on the basis of the superposition of eigenmode fields thus obtained. Numerical results in the case of four, five, and six cores indicate that coupling strength is not always a periodic function of propagation length unlike the case of dual-core structures
