论文摘要
我们展示了基于高性能AOM的双频干涉仪，可以实现单个光子级量子状态的跳动或跳动的自由干扰。干涉仪的可见性和光学效率分别为（99.5 +-0.2）％和（95 +-1）％。干涉仪的相位通过使用抖动相位锁定方案来积极稳定，在该方案中，通过直接使用特殊设计的电子信号驱动AOM来实现相位抖动。我们进一步证明了干涉仪在量子技术中的应用，包括双频相干组合，频率调整和光学切换。这些结果表明，干涉仪是用于多种量子技术的多功能设备。
We demonstrate a high performance AOM based bi-frequency interferometer, which can realize either beating or beating free interference for single photon level quantum state. Visibility and optical efficiency of the interferometer are (99.5 +- 0.2)% and (95 +- 1)%, respectively. The phase of the interferometer is actively stabilized by using dithering phase locking scheme, where the phase dithering is realized by directly driving the AOMs with specially designed electronic signal. We further demonstrate applications of the interferometer in quantum technology, including bi-frequency coherent combination, frequency tuning and optical switching. These result show the interferometer is a versatile device for multiple quantum technologies.
