  • Description: Since spectral broadening of a weak, picosecond pulse (I2 pulse) was observed due to phase-modulation induced (IPM) by a second, independent and intense pulse (I1 pulse) at a different wavelength in condensed media [1], picosecond or femtosecond pulse compressions using IPM in fibers were proposed and analyzed [2–7]. However, IPM phenomena in the femtosecond time-region in fibers have not been yet made clear experimentally. In this paper, we report the first observation of IPM for femtosecond pulses propagating in a fused-silica glass fiber (glass fiber) and a DAN (4-(N, N-dimethylamino)-3-acetamidonitrobenzene) single crystal-cored fiber (DAN fiber) [8]. Furthermore, it is shown that the latter’s ultrafast nonlinear refractive index n2.DAN, whose value has been so far unknown to our knowledge, is much larger than the former’s n2.G.
