1.5μm correlated photon pair generation in high nonlinear microstructure fibre

We realize the correlated photon pair generation at 1.5μm by spontaneous four-wave mixing in high nonlinear microstructure fibre with a length of 25m, showing that high nonlinear microstructure fibres have great potential in bright, high efficiency and compact sources of correlated photon pairs at 1.5μm.
