Abstract :
A novel nondestructive technique for characterising couplers by means of a local perturbation is described. The method is studied theoretically and verified experimentally by characterising different types of fused fiber-couplers. Using this technique, both the information of the power distribution and coupling profile along the coupler waist are obtained
