Abstract: A train of transform-limited optical pulses with wavelength close to the zero-dispersion wavelength of the fibre (2) and high and variable peak power, such as to give rise to self-phase modulation, is sent into a fibre (2); the spectral broadening of the signal exiting the fibre (2) is measured for a number of values of the peak power of the pulses and the nonlinear refractive index is obtained from the angular coefficient of the straight line representing spectral broadening versus peak power. The device for carrying out the method is also provided.

Abstract: To measure the nonlinear refractive index of an optical fibre, each pulse emitted by a source (L) is split into a pair of pulses which are sent in opposite directions into an optical-fibre Sagnac interferometric loop (AS) which includes the fibre under test (F). One of the pulses of the pair is attenuated before passing through the fibre (F) in such a way that only the other one has such a power as to induce nonlinear effects in the fibre (F). The interference between parts of pulses is analysed at the output of the loop (AS) and the nonlinear refractive index is derived from a measurement of the phase shift between the two pulses of the pair.
