| Popis: |
Photonic crystal fibres (PCF) can be tailored to introduce a high effective nonlinear Kerr effect and to create lower amounts of excess noise compared to standard fibres. Taking advantage of these features and using ultrashort pulses we create polarisation squeezed states with notably higher purity than obtained in standard fibres. The squeezed states are produced by pulses of equal polarisation counter propagating along the same fibre axis undergoing nearly identical spectral and temporal changes (Fig.1). Overlapping these pulses in modes of mutually orthogonal polarisation enables the production of polarisation squeezing. |
