Macroscopic crystalline whispering gallery mode resonators (WGMR) made out of LiNbO3 are a versatile source of non-classical light generated via optical parametric down-conversion [1]. This is a process where one photon is split into two photons called signal and idler. Both photons are correlated due to energy conservation, which affects the statistical fluctuations in certain measurements. We report how non-classical light can be efficiently generated and present the prospects of possible applications within the field of optomechanics [2].
