We present a review of our recent research on the use of photonic crystal fibers (PCFs) to manipulate the propagation of ultrashort pulses. The combination of a high nonlinear coefficient and unusual wavelength-dependent group-velocity-dispersion "landscapes", together with the ability to taper the properties along the fiber by thermal post-processing, allows observation of many interesting effects. These include generation of THz trains of equidistant sub-50 fs pulses, highly efficient supercontinuum generation from the UV to the IR, soliton collisions and observation for the first time of a soliton blue-shift, counteracting the Raman-related soliton self-frequency shift.
