GUTIERREZ, J.G. et al. Influencia de la inestabilidad modulacional en la generación de un espectro continuo en fibras ópticas con pulsos de nanosegundos. Rev. mex. fis. [online]. 2009, vol.55, n.5, pp.359-366. ISSN 0035-001X.

In this work the influence of modulational instability on the supercontinuum generation in standard optical fibers in the anomalous dispersión regime is reported. A 30 ns pump pulse with wavelength equal to 1549 nm from a directly modulated DFB laser was used. Results show that the spectrum broadening is due to modulational instability and self frequency shift. The spectrum broadening was depending of fiber length and pump power.
