Chromatic dispersion measurement of optical fibres using interferometric technique
Dymák, Pavel ; Peterka, Pavel
Research report deals with measurement of chromatic dispersion of singlemode optical fibres using interferometric technique at IREE AS CR in Prague. The document describes in details all components of measurement setup, initial setting up and measurement procedure, using of assembled control programs and the measurement data processing too. Several tips and practical recommendations complete the report based on many performed experiments.
Chromatic dispersion measurement of erbium-doped optical fibres using interferometric technique
Dymák, Pavel ; Peterka, Pavel
Chromatic dispersion measurement on short lengths of erbium-doped optical fibres by the interferometric technique is presented. The resonant dispersion induced by Er3+ ion is calculated from the experimental absortion and emission cross sections.
Measurement of intermodal dispersion in a twin-core optical fibre
Peterka, Pavel ; Kaňka, Jiří ; Honzátko, Pavel
The intermodal dispersion (IMD), that arises from the difference of group delays of the two fundamental modes of the twin-core fibre (TCF), could have a detrimental effect for usage of TCF in high-speed applications. Therefore, its accurate determination is of a high interest. We have estimated the IMD from the fibre refractive index profile and we have determined it from the interference pattern in spectral domain and from the repetition rate of passively mode-locked fibre laser incorporating TCF.
Measurement of chromatic dispersion and berifringence of microstructure optical fibers
Peterka, Pavel ; Dymák, Pavel ; Honzátko, Pavel ; Matějec, Vlastimil ; Kaňka, Jiří ; Martan, Tomáš ; Vraný, Boleslav ; Káčik, D. ; Lyytikainen, K.
Chromatic dispersion characterization of the microstructure optical fibres /MOF/ using the interferometric method is shown on several fibre samples. The differences from the measurement of standard single mode fibres are discussed.
