Abstract :
Generalised coupled-mode equations for two or more coupled weakly guiding fibres are presented, when the fibres are not well separated. These equations are applied to studying fibre couplers. Compared with the results derived from previous coupled-mode equations, our results are in better agreement with those calculated rigorously by a numerical method.
