A controlled helix pitch modulation in the in-plane direction of a planarly aligned cholesteric liquid crystal cell is demonstrated by using photopolymerizable cholesteric liquid crystals. By fabricating artificial domains with a closed volume via two-photon excitation laser-lithography, the degree of pitch modulation could be controlled by adjusting the surface area to volume ratio of the domain. A pitch modulation of over 60 nm was realized by designing the shape of the artificial domain.
通过使用可光聚合的胆甾相液晶，展示了在平面排列的胆甾相液晶盒的面内方向上进行可控的螺旋节距调制。通过双光子激发激光光刻制造具有封闭体积的人工畴，节距调制程度可通过调整畴的表面积与体积比来控制。通过设计人工畴的形状，实现了超过60纳米的节距调制。
