Non-classical interference in integrated 3D multiports

Thomas Meany, Michael Delanty, Simon Gross, Graham D. Marshall, M. J. Steel, Michael J. Withford

摘要:

我们展示了三个和四个输入多端口在三维玻璃平台,使用飞秒激光直写技术制造。Hong-Ou-Mandel(HOM)干涉被观察到,并进行了完整的量子表征,获得了输入和输出端口的所有组合的双光子相关矩阵。对于三端口的情况下,准确地预测量子vibrium仅从测量的经典耦合比。

英文摘要:

We demonstrate three and four input multiports in a three dimensional glass platform, fabricated using the femtosecond laser direct-write technique. Hong-Ou-Mandel (HOM) interference is observed and a full quantum characterisation is performed, obtaining two photon correlation matrices for all combinations of input and output ports. For the three-port case, the quantum visibilities are accurately predicted solely from measurement of the classical coupling ratios.
