Abstract
By using a frequency resolved optical gating to characterise an optical pulse both before and after propagation in a length of standard singlemode fibre, the authors have simultaneously determined the fibre's nonlinear refractive index n2 and group velocity dispersion. Over the wavelength range 1534–1559 nm, an average n2 = (2.53 ± 0.09) × 10-20 m2 W-1 (linear polarisation) was measured and dispersion characteristics which are in good agreement with specifications were obtained.Keywords
