A equação de modo acoplado que descreve a propagação da luz em um sistema de guia de ondas desordenado composto de núcleos aleatoriamente diferentes em tamanho é resolvida analiticamente pelo método de perturbação e a amplitude média da luz é derivada. Na soma de uma série de perturbações apenas são levados em consideração dispersões sucessivas de diferentes núcleos. O resultado obtido mostra que a amplitude média se comporta como se estivesse em um sistema ordenado de guias de ondas composto por núcleos idênticos a curta distância e diminui exponencialmente com o aumento da distância em grandes distâncias. O resultado é comparado com o resultado obtido pela aproximação do potencial coerente e ambos os resultados estão em boa concordância entre si. Os resultados também são comparados com os resultados obtidos pela resolução numérica da equação do modo acoplado.

Abstract: The coupled mode equation describing the propagation of light in a disordered waveguide system composed of randomly different cores in size is analytically solved by the perturbation method and the average amplitude of light is derived. In the summation of a perturbation series only successive scatterings from different cores are taken into account. The result obtained shows that the average amplitude behaves as if in an ordered waveguide system composed of identical cores at short distance and decreases exponentially with increasing distance at large distance. The result is compared with the result obtained by the coherent potential approximation and the both results are in good agreement with each other. The results are also compared with the results obtained by numerically solving the coupled mode equation.
