Ferroelectric nematic liquid crystals (FNLC), known for their responsiveness to influences, are highly valued for their precise adjustment of optical properties in real-time, a crucial aspect for applications in quantum optics . Sultanov and colleagues discovered the phenomenon of SPDC (spontaneous down conversion) in a nematic liquid crystal (FNLC) for the first time, marking a significant milestone in liquid crystal and organic material research [18]. The FNLC exhibited a rate comparable to top nonlinear crystals, showcasing the potential of FNLCs as effective generators of entangled photons.
