Abstract
Polarization entanglement has not yet been shown in crystalline whispering gallery resonators. Here, we generate polarization entanglement by using an interferometric scheme. The S value of the Clauser-Horne-Shimony-Holt’s inequality in the system is 2.54 ± 0.06, in clear violation of the local realism.
