基于铁电向列相液晶微结构的非线性光场调控

摘要：

铁电向列相液晶（FNLCs）兼具流体可加工性与高二阶非线性极化率，为“软物质光子学”提供了重要平台。本报告展示了通过光取向FNLC微结构实现的非线性光场调控。通过发现具有周期性调制单极/双极有序度的新型NX中间相，我们实现了可设计、无缺陷的面内极性畴工程。基于此，利用单层微米级器件直接产生了倍频完美矢量光束。此外，我们在离子掺杂FNLC中实现了可重构非线性几何相位（PB相位）调控。通过对非线性PB相位进行空间调制，利用极低电场（0.06 V/μm）实现了程序化光束偏转及倍频信号的动态控制。这些研究为微缩化、可重构的非线性光子应用奠定了基础。

Title

Nonlinear Light Field Manipulation via Ferroelectric Nematic Microstructures

Abstract：

Ferroelectric nematic liquid crystals (FNLCs) combine fluidic processability with high second-order nonlinear susceptibility, providing a versatile platform for "Soft Mattonics". We present nonlinear light field manipulation via photopatterned FNLC microstructures. By discovering a novel NX mesophase featuring periodically-modulated unipolar and bipolar orders, we achieve designable, defect-free in-plane domain engineering. This allows the direct generation of second-harmonic perfect vector beams from a single-layer, micrometer-thin device. Additionally, we demonstrate reconfigurable nonlinear Pancharatnam-Berry (PB) optics using ion-doped FNLCs. Spatial modulation of the nonlinear PB phase enables programmable beam steering and dynamic control of second-harmonic signals under ultra-low electric fields (0.06 V/μm). These advancements establish a foundation for miniaturized and reconfigurable nonlinear photonic applications.
