Parametrically polarization-shaped pulses via a hollow-core photonic crystal fiber

We present a procedure to generate parametrically shaped pulses after propagation through a microstructured hollow-core photonic crystal fiber. The properties of the fiber are characterized and employed to analytically design sequences of subpulses which are available after the fiber. In these sequences, each subpulse can be individually controlled in its physically intuitive parameters: position in time, energy, phase, and chirp as well as the polarization state with orientation, ellipticity, and helicity. Various endoscopic applications may arise from this approach.
