Record nonlinearity in optical fibre

Record nonlinearity in optical fibre

A record effective fibre nonlinearity of 5,400 W^sup -1^ km^sup -1^ at 1,550 nm has been measured in a non-tapered bismuth microstructured optical fibre. This extremely high nonlinearity has been achieved by fabricating a fibre with a suspended-nanowire structure with a core diameter of only 530 nm....

Zusammenfassung:A record effective fibre nonlinearity of 5,400 W^sup -1^ km^sup -1^ at 1,550 nm has been measured in a non-tapered bismuth microstructured optical fibre. This extremely high nonlinearity has been achieved by fabricating a fibre with a suspended-nanowire structure with a core diameter of only 530 nm. The nonlinear phase shift is measured using the dual-frequency, self-phase modulation method. This result demonstrates the potential of this emerging class of fibres for use in compact nonlinear devices.
