摘要: A new technique for measuring equivalent-step-index profiles of monomode fibres is presented which involves the mode spot-size directly as a function wavelength, and compares favourably with measured profiles. Since characterisation fibre derived from easily optical properties, knowledge actual profile modelling propagation characteristics it unnecessary.
