摘要

在电信波长上生成高效的片上纠缠光子对是新兴量子光学技术不可或缺的一个方面,特别是在量子通信和计算方面。然而,转向更短的波长可以使用更容易获得的硅探测器技术,并开辟了成像和光谱学的应用领域。在这里,我们展示了在周期性极化铌酸锂纳米光子波导中产生的高亮度((1.6 ± 0.3)×109 对/s/mW/nm)可见光-近红外光子对。当使用光谱多模激光二极管泵浦时,光子对的退化光谱以 811 nm 为中心,带宽为 117 nm。测得的片上光源效率为 (2.3 ± 0.5) × 1011 pairs/s/mW,与电信波长的光源效率相当,也比基于体晶体或扩散波导技术的其他可见光光源效率高几个数量级。通过使用单频激光对器件进行泵浦,还可以进一步提高亮度和效率,这也会缩小光对带宽。这些结果代表了迄今所报道的在纳米光子波导中产生的光子对的最短波长,将近八度。

Highly efficient visible and near-IR photon pair generation with thin-film lithium niobate
Efficient on-chip entangled photon pair generation at telecom wavelengths is an integral aspect of emerging quantum optical technologies, particularly for quantum communication and computing. However, moving to shorter wavelengths enables the use of more accessible silicon detector technology, and opens up applications in imaging and spectroscopy. Here, we present high brightness ((1.6 ± 0.3) × 109 pairs/s/mW/nm) visible–near-IR photon pair generation in a periodically poled lithium niobate nanophotonic waveguide. The degenerate spectrum of the photon pairs is centered at 811 nm with a bandwidth of 117 nm when pumped with a spectrally multimode laser diode. The measured on-chip source efficiency of (2.3 ± 0.5) × 1011 pairs/s/mW is on par with source efficiencies at telecom wavelengths and is also orders of magnitude higher than the efficiencies of other visible sources implemented in bulk crystal or diffused waveguide-based technologies. Further improvements in the brightness and efficiencies are possible by pumping the device with a single-frequency laser, which would also shrink the pair bandwidth. These results represent the shortest wavelength of photon pairs generated in a nanophotonic waveguide reported to date by nearly an octave.
