Abstract

By coupling 110fs pulses at λ=1.55µm into a 45cm long holey fiber, we observe the generation of a broadband continuum, followed by the appearance of a sharp blue line at 430nm. Blue light is generated in a high-order mode by a third-harmonic generation process that is phase-matched with the super-continuum component at 1.29µm. Such an interpretation is supported by measurements performed by using 1.29µm pulses and also by simulation. In addition we find that the choice of an input polarization tilted with respect to the fiber-birefringence axis can lead to the generation of new frequencies through a four-wave mixing process that exploits non-diagonal components of the third-order susceptibility.
