       我们课题组的研究工作力图做到两点（显然还没有完全达到^V^）：一、有特色的开创性；所以有些小众，关注点和切入点与流行风尚保持一定的距离。二、科学知识的探索性研究和实际应用的技术研发相结合，形成了基础物理、实验探索、应用开发相结合的研究链条；所以是多学科的交叉，研究既需要一定的深度也需要一定的广度。

       我们的研究方向主要集中在飞秒激光与晶体材料的作用上，尤其注重对瞬态元激发的理解和应用，涉及超快光子学、超快光学、太赫兹光学、光电材料与器件、微纳光子学、凝聚态物理等方面。在该研究方向上，有两方面的研究内容：一是飞秒激光改性晶体的物理机理、材料制备及其器件应用；二是铁电晶体中飞秒激光激发太赫兹声子极化激元的物理与应用。

 目前，比较有代表性的结果有：

一、飞秒激光改性晶体材料的物理机理

       在前人的基础上，我们发展了三维双温德鲁得模型，并考虑声子等元激发的作用，提出了竞争模型，解释了飞秒激光与晶体材料作用的一些基本规律。在竞争模型和材料改性过程中等离子体性质的研究基础上，建立飞秒激光改性硅材料的微观机制框架。

       基于对声子等元激发的理解，实现了飞秒激光改性晶体材料过程中的元激发的调控与应用。实验结果证明了物理模型的正确性，并大幅提高了改性材料的质量和制备的光电探测器、微纳结构器件的性能。

三、太赫波的时空超分辨成像、荧光四维成像（时间分辨三维空间荧光成像）

        发展了太赫兹波的时空超分辨成像系统，实现了定量分析，并进一步提高了成像质量。目前空间分辨率是太赫兹波长的几十分之一，时间分辨率是一个太赫兹电磁振荡周期的十分之一，实现了时空的超分辨成像和定量分析。

       结合宽场荧光寿命成像技术和远程重聚焦系统，搭建了一套时间分辨三维荧光光谱系统。这套系统可以在不扰动样品的情况下，实现空间三维、时间分辨的光谱成像。这套系统的时间分辨率可以达到30皮秒，空间分辨率1微米，光谱范围从300 nm至900 nm。该系统有望在物理、化学、生物等方面的瞬态研究中得到应用。

四、基于铌酸锂亚波长晶片的太赫兹集成与应用（欢迎产业界合作）

       电子学和光子学的发展日益完善，使得科研工作者们把目光集中在频段介于两者之间曾经被称为“太赫兹空白”的太赫兹技术和科学。很多太赫兹波独有的优势被挖掘出来，例如无损探测、生物成像、天文研究和远距离通讯等。鉴于这些优势，人们开始寻求一个太赫兹的集成化平台，像电子学的集成电路和光子学中的光子集成回路那样，使太赫兹波的产生、传输、调控、探测等过程以及太赫兹波和物质或结构的作用过程在同一个平台上实现，以利于太赫兹技术的实际应用。

       利用亚波长铌酸锂晶片作为基质材料，我们实现了太赫兹波的产生、传输、调控、探测、与物质或微结构的相互作用等功能的片上集成。这样形成的太赫兹芯片是太赫兹波应用的一种有效方式。近期，在灵敏传感探测、片上集成太赫兹时域光谱、未来片上通讯（beyond 6G）等方面都展现了非常令人兴奋的潜在应用。

五、亚波长瞬态光学、光子学与元激发的非线性物理和量子物理

       基于铌酸锂太赫兹芯片的时空超分辨成像系统，我们展开了亚波长瞬态光学、光子学的研究和元激发（主要指声子极化激元）的非线性物理和量子物理的研究。这个工作不仅可以开发新的方程和理论，纠正教科书中公式的适用范围，同时也是众多实际应用研究的理论基础。

        例如，随着纳米光子学的发展，对于稳态亚波长光学的研究，尤其是在各向同性的材料中，利用数值软件可以进行非常优秀的模拟、设计和分析。但是，有些瞬态过程的实验结果不仅与数值模拟不符，而且与人们的直觉认识也不一样。我们发现，亚波长波导的耦合过程中，达到稳态模式后，还需要在时间上经历一定的阻尼振荡过程；对于亚波长矩形波导，教科书中最普遍使用的Marcatili方法不再适用等。如果再考虑晶体的各向异性，再考虑光和物质相互作用中的物质方程的瞬态作用，物理问题变得更加复杂。这个领域充满了未知！
