Near-infrared Hong-Ou-Mandel interference on a silicon quantum photonic circuit
Xinan Xu, Zhenda Xie, Jiangjun Zheng +9
Near-infrared Hong-Ou-Mandel quantum interference is observed in silicon nanophotonic directional couplers with raw visibilities on-chip at 90.5%. Spectrally-bright 1557-nm two-pho…

Efficient single-spatial-mode periodically-poled KTiOPO_4 waveguide source for high-dimensional entanglement-based quantum key distribution
Tian Zhong, Franco N. C. Wong, Alessandro Restelli +1
We demonstrate generation of high-purity photon pairs at 1560 nm in a single spatial mode from a periodically-poled KTiOPO_4 (PPKTP) waveguide. With nearly lossless spectral filter…
