Method and apparatus for determining the polarisation mode dispersion of an optical device

摘要: A method and an apparatus for determination of properties, e.g. elements of the Jones matrix, optical device under test, comprising steps of: generating a coherent light beam, splitting beam into first beam and second coupling with given initial polarization letting beam travel different path as superimposing to generate interference between in resulting superimposed the superimposed third polarization dependent a fourth continuously detecting power fourth light function frequency when tuning the coherent from minimum maximum range, deriving transmissive elements the frequency dependency detected power.
