Abstract | ||||
In the frame of a large stroke optical fibre delay line implementation, we report experimental work focused on the full analysis of chromatic dispersion evolution versus fibre stretching. The delay line is tested in a fibre Mach-Zehnder interferometer. The experimental work is carried out using a spectral analysis of the interferometric mixing. A linear variation of the second order chromatic differential dispersion is observed versus high stretching. The stretched fibre dispersion evolution is scaled by comparison with unstretched fibre samples generating an equivalent group delay. | ||||
