Procedure for determining the wavelength in an optical fibre corresponding to zero dispersion. |
摘要 |
The measuring system uses 2 light signals of different wavelength fed to the light conductor (4) and detection of the product obtained by the non-linear interaction of the light signals, via an analyser (3). The wavelength of one of the light signals is varied until the optical power of the product is a max. with the zero dispersion point indicated by the wavelength when this is obtained. The second wavelength is selected to be outside the range of the expected zero dispersion point. <IMAGE> |
