The determination of the refractive index profile in α-profile optical fibres by intermodal interference investigation
Abstract:A way of determination of α-parameter for α-profile optical fibres is presented in the paper. The determination is based on the dependence of the ratio of equalisation wavelengths of the LP01–LP11 and LP01–LP02 mode pairs on the α-parameter. The application of the method is illustrated on the measurement of a Lucent AllWave fiber.
