We demonstrate a picosecond source of correlated photon pairs using a micro-structured fibre with zero dispersion around 715 nm wavelength. The fibre is pumped in the normal dispersion regime at ~708 nm and phase matching is satisfied for widely spaced parametric wavelengths. Here we generate up to 10;7 photon pairs per second in the fibre at wavelengths of 587 nm and 897 nm, while on collecting this light in single-mode-fibre-coupled Silicon avalanche diode photon counting detectors, we detect ~3.2x10;5 coincidences per second at pump power 0.5 mW.
我们展示了一种皮秒级关联光子对源,它使用了一种在715nm波长附近具有零色散的微结构光纤。该光纤在约708nm的正常色散区域泵浦,并且对于间隔较大的参量波长满足相位匹配。在此,我们在光纤中以587nm和897nm的波长每秒产生多达10⁷个光子对,而当在单模光纤耦合的硅雪崩二极管光子计数探测器中收集此光时,在0.5mW的泵浦功率下,我们每秒检测到约3.2×10⁵个符合计数。
