Gr. Boyer et al., FEMTOSECOND PULSE-SHAPING SCHEME FOR CROSS-PHASE MODULATION IN SINGLE-MODE OPTICAL FIBERS, Journal of the Optical Society of America. B, Optical physics, 11(8), 1994, pp. 1451-1455
We report a pump-probe cross-phase-modulation experiment in a single-m
ode optical fiber in which the probe spectrum is shifted by an amount
comparable with its spectral width under the influence of a 250-pJ pum
p pulse. The pulses are 210 fs FWHM and are generated by the reshaping
of the pulses of a femtosecond Ti:sapphire laser. The dependence of t
he wavelength shift on the pump-probe delay time is investigated, and
the results are found to be in good agreement with numerical simulatio
ns. Application to all-optical femtosecond switching is discussed.
