Materials with high nonlinear optical (NLO) susceptibilities are considered as potential candidates for the next-generation NLO devices. Ferroelectric nematic (N-F) materials are argued to have the potential to become materials for the next-generation NLO devices. We conducted a study on a prototype N-F material and found a high nonlinear susceptibility in the transparent regime, which is one of the highest reported in ferroelectric liquid crystals. Despite the fact that the studied molecule was not specifically designed for NLO applications, it is concluded that there is still potential to obtain N-F materials with enhanced properties.
Materials that exhibit high nonlinear optical (NLO) susceptibilities are considered as promising candidates for a wide range of photonic and electronic applications. Here, we argue that the ferroelectric nematic (N-F) materials have sufficient potentialities to become materials for the next-generation of NLO devices. We have carried out a study of the efficiency of optical second-harmonic generation in a prototype N-F material, finding a nonlinear susceptibility of 5.6 pm.V-1 in the transparent regime, one of the highest ever reported in ferroelectric liquid crystals. Given the fact that the studied molecule was not specifically designed for NLO applications, we conclude there is still margin to obtain N-F materials with enhanced properties that should allow their practical use.
