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.

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.
