摘要
We present a wavelength-tunable narrow-band fiber-coupled source to generate correlated photon pairs at 539 nm and 1550 nm. Using a 10-mm PPLN crystal, we obtain more than 50 mm tunable range near 1550 nm. This source, given its spectral property and tunable property, is well suited for tasks in fiber-optic quantum communication and cryptography networks.
