Ultrabright narrow-band telecom two-photon source for long-distance quantum communication
Kazuya Niizeki, Kohei Ikeda, Mingyang Zheng +7
We demonstrate an ultrabright narrow-band two-photon source at the 1.5 -μm telecom wavelength for long-distance quantum communication. By utilizing a bow-tie cavity, we obtain a ca…
