Strain-optic coefficients of individual cladding modes of singlemode fibre : Theory and experiment


  • Chen, Chengkun
  • Albert, Jacques




The different strain-optic coefficients for the effective indices of the core and cladding modes of a standard telecom singlemode fibre are measured by stretching a fibre in which a 4-tilted fibre Bragg grating has been written. The origin of the modal dependence of the strainoptic coefficient differences is analysed and discussed. Good agreement between theoretical and experimental values of these coefficients is reported.
