| Abstract: | A generalized definition of LP modes is introduced for an optical fiber with arbitrary refractive-index profile and arbitrary cross section, The orthogonality property of these LP modes has been considered. Based on a complete set of LP modes in a chosen reference fiber, a set of coupled-mode equations describing a practical fiber are established. Possible applications of these coupled-mode equations are demonstrated. |
