Single-photon level ultrafast all-optical switching
Xiao-Feng Han, Yu-Xiang Weng, Rui Wang, Xi-Hao Chen, Kai-Hong Luo et al.
We demonstrate an approach to all-optical switching, where a weak beam controls a strong beam, based on three-wave mixing optical parametric amplification in a nonlinear crystal. Ultrafast switching within 400 fs has been achieved with a 130 fs single-photon level switch beam containing, on averag ... [Appl. Phys. Lett. 92, 151109 (2008)] published Thu Apr 17, 2008.
