标题： Fully-chromophoric ferroelectric nematics for electronic electro-optics

摘要： 电子电光（EEO）相位调制是芯片尺度上电子和光子域之间信号转换的关键新兴技术。 最近发现的铁电向列（$N_F$）液晶相，是一种由棒状有机分子组成的三维流体，具有近乎完美的平衡极性分子取向有序性，为创建用于EEO的二阶非线性光学材料提供了有吸引力的机会。 在这里，我们提出并实现了一种NF EEO分子的设计模式，其中几纳米长的分子棒既被功能化以进行静电端对端结合，促进NF相的形成，又被功能化以产生色团光学非线性，从而实现高EEO效率，这种组合使得一种100%为色团的主动二阶非线性EEO介质成为可能。 显示英文摘要

摘要： Electronic electro-optic (EEO) phase modulation is a key emerging technology for the chip-scale inter-conversion of signals between the electronic and photonic domains. The recent discovery of the ferroelectric nematic ($N_F$) liquid crystal phase, a three dimensional fluid of rod-shaped organic molecules having near-perfect equilibrium polar molecular orientational order, offers attractive opportunities for the creation of second-order nonlinear optical materials for EEO. Here we propose and realize a design motif for NF EEO molecules in which few-nanometer-long molecular rods are functionalized both for electro-static end-to-end association, facilitating NF phase formation, and for chromophoric optical nonlinearity, enabling high EEO efficiency, a combination enabling an active second-order nonlinear EEO medium that is 100% chromophoric.
