Abstract :
Loss of temporal coherence is observed in a two-beam interferometer composed of 1800 m-long fibres with 1.3 ¿m and 1.5 ¿m zero chromatic dispersion wavelengths. Experimental results fully explain and reflect theoretically predicted ones concerning both the magnitude of degree of coherence and the shape of the coherence curve with respect to the optical path difference.
