Bright source of indistinguishable photons based on cavity-enhanced parametric down-conversion utilizing the cluster effect

Applied Physics Letters, 108(2).

We present a bright, simple-to-setup, single-mode source of indistinguishable photon pairs at the cesium D1 -line with a bandwidth of about 100 MHz. The source is based on degenerate, cavity-enhanced spontaneous parametric down-conversion utilizing the cluster effect. The setup relies on a microcontroller-based digital locking system. A brightness of 1.1x10^3/(s mW) detected, indistinguishable photon pairs could be measured.
