新策略实现宽频带纳米光场精准操控
Ke Ji Ri Bao· 2025-12-16 00:16
如何实现光在纳米甚至原子尺度上的精准操控与高效传播,一直是科学研究的前沿问题。近日,来自上 海交通大学、国家纳米科学中心、东北师范大学与香港大学的联合研究团队,提出了一种名为"声子工 程"的新策略,首次实现了超宽频带、几乎无衍射的极化激元定向传播。相关研究成果15日发表于《自 然·纳米技术》杂志。 "我们不再是被动地寻找满足动量匹配的体系,而是主动'设计'出理想状态。"论文共同通讯作者、上海 交通大学副教授郭相东说,"这为制造超紧凑、高性能的光子电路打开了一扇全新的大门,也为纳米光 子学与集成光电子学的未来发展注入强大动力。" "'声子工程'调控策略不仅解决了极化激元控制中的关键技术瓶颈,还具有较强的通用性和灵活性。"戴 庆说,借助该技术,未来有望在指甲盖大小芯片上集成强大的光子电路,推动信息技术向更高速、更低 功耗、更高密度方向发展。 (文章来源:科技日报) 然而,要将这一潜力转化为现实,首先必须解决一个核心难题:如何对极化激元进行高效且灵活的控 制。目前,该操控过程面临两大技术瓶颈。论文共同通讯作者、上海交通大学教授戴庆告诉记者:"首 先是需要非常精确的'动量匹配',就像两列火车要完美同步才能对接;其次是 ...
