LICEA RODRIGUEZ, J.; GARAY PALMETT, K.  y  RANGEL ROJO, R.. Femtosecond pulse source based on soliton filtering from a supercontinuum generated in a microstructured fiber. Rev. mex. fis. [online]. 2010, vol.56, n.4, pp.311-316. ISSN 0035-001X.

In this article we report the implementation of a tunable source of ultrashort pulses, based on the generation of a supercontinuum in a photonic crystal fiber, using sub-100 fs pulses from a Ti:sapphire oscillator, and filtering the soliton with the longest wavelength out of the continuum. Using a zero dispersion filtering system we were able to get a pulse duration close to the minimum possible for the soliton. The pulses obtained were continuously tunable in the 850-1100 nm range, and tuning was achieved by input pulse energy variation. We present a complete characterization of the filtered pulses and show that the experimental results have a qualitative agreement with theory.

Palabras llave : Optical solitons; ultrashort pulses; solitons in optical fibers.
