摘要：本文提出一种基于液晶高分子薄膜的等功率分束器,通过多角度偏振图案化光取向精准操控液晶分子二维平面内的取向,设计并制备了基于Y型功率分束器模型的1×2等功率分束器。通过优化弯曲波导的半径,开发了分束间距分别为80μm和160μm两种分束器,并进一步将二者集联,构建了分束间距均等的1×4等功率分束器。实验结果表明,所设计的分束器在液晶波导中实现了光的并行传输与等功率分配,为液晶波导器件的功能拓展提供了有效解决方案。该研究为液晶高分子波导的集成化与小型化发展开辟了新路径,具有广泛应用于光计算和光通信等领域的潜力。
This study proposes a liquid crystal polymer-based equal-power splitter.Through multi-angle polarized patterned photoalignment,precise control of liquid crystal molecular orientation in a two-dimensional plane was achieved,enabling the fabrication of a 1×2 equal-power splitter based on a Y-shaped splitter model.By optimizing the bending radius of the waveguide,two types of splitters with spacing of 80μm and 160μm were developed.Furthermore,these splitters were cascaded to construct a 1×4 equal-power splitter with uniform spacing.Experimental results demonstrate that parallel light transmission and equal-power distribution within the liquid crystal waveguides are achieved,providing an effective solution for enhancing the functionality of liquid crystal waveguide devices.This research offers a new approach for advancing the integration and miniaturization of liquid crystal polymer waveguides,with potential applications in optical computing and optical communication.
