Chiral ferroelectric nematic liquid crystals as materials for versatile laser devices
César L. Folcia, Josu Ortega, Teresa Sierra +2
We present a liquid-crystal laser device based on the chiral ferroelectric nematic phase (NF*). The laser medium is obtained by mixing a ferroelectric nematic material with a chira…

Second harmonic generation in anisotropic stratified media: A generalization of the Berreman method and its application to photonic materials
J. Ortega, C. L. Folcia, J. Etxebarria
We have developed a numerical method for calculating the second harmonic generation (SHG) generated by an anisotropic material whose optical properties present an arbitrary modulat…
