点亮微观世界——基于有机异质结的双色微激光器

激光是20世纪人类最伟大的发明之一，具有方向性、单色性、高亮度等特点，是目前人类利用光的信息和能量最有效的方式，被称为最快的刀、最准的尺、最亮的光，由此衍生出来的激光切割、激光测距、激光通信等一系列革命性技术，已经在军事国防、工业生产和人们日常生活的诸多领域得到了极大应用。双色（或多色）激光光源，近年来引起了科学家和大众的广泛关注，被认为是实现未来并行量子计算、激光显示、激光照明等突破性科技的关键源头技术。然而，由于组成激光三要素之一的增益介质（另外两者为谐振腔和泵浦源）一般只具有较窄的光学增益窗口，使得常见激光器只能发出单一颜色的信号光。而通常实现双色或多色激光的办法，是将不同颜色的激光并行合束在一起，这往往使得激光器的尺寸较大，不利于微型集成。

半导体微纳米异质结，是近年来兴起的构筑双色激光器理想的微结构材料。它是将不同颜色的半导体介质通过外延生长的方法，紧密集成在一块只有人体头发丝直径1/100尺寸大小的纳米材料上，利用半导体纳米材料的自谐振腔和增益特性，可以实现超小体积和能耗的激光输出。传统的纳米异质结，一般是利用无机半导体在高温或高压的条件下，通过气相沉积或水热法制备得到，异质结构的生长需要满足严格的晶格匹配推荐。相较而言，有机半导体纳米异质结构，由于弱的分子间相互作用及良好的分子兼容性，易于在温和条件下通过溶液组装的方式，进行快速、大批量地制备。然而，由于缺乏对二元分子协同组装机制的深入理解，目前将两种以上激光染料分子可控组装成高质量的复合谐振腔结构，并保持它们各自的微腔和增益特性，仍然面临很大地挑战。

最近，北京师范大学呼凤琴课题组和中科院化学研究所赵永生课题组合作，通过分步协同组装，可控制备得到了一类蓝色微盘（WGM腔）和绿色微米线（FP腔）组成的双色激光器。他们从能级增益和分子间相互作用的角度出发，结合理论计算，设计合成了两种母体相同但取代基不同的激发态分子内质子转移（ESIPT）激光染料分子。两种分子共同具有四能级辐射类型的激发态过程，各自的晶态聚集体都能实现高效的激光出射，同时相似的分子微观堆积作用和分子间氢键相互作用，为两种分子协同组装从而得到高质量的复合谐振腔结构提供了可能。研究表明，两种分子分步协同组装策略的作用机制，与通过理论预想的一致，涉及方向性氢键辅助的晶面选择性成核生长。即一种有机分子先行组装成微盘，另一种分子在分子间氢键作用下选择性地在微盘特定晶面（010）或（0-10）成核进而外延生长得到微米线，进而可控地制备了线/盘复合的耦合谐振腔结构。在外部光源的激励下，该异质结构能够同时在微米线两端可控地输出蓝色和绿色激光，两种激光信号的强度可以被有效地调控，激光输出波长可以在蓝光和绿光之间连续切换。

该工作为多色甚至白光激光的开发提供了新的思路，也为多带片上集成和并行运算提供了初步的结构论证和材料基础。相关论文发表在Advanced Optical Materials（DOI: 10.1002/adom.201701077）上。

化学所赵永生首次利用静电场在微纳体系打破光传输的对称性

与p-n结在微电子器件中的作用一样，光学二极管在光子回路中的作用至关重要。不同于电子的运动行为，光子传输通常是互易的，而且光子是不带电荷、没有静质量的玻色子，其传输行为很难通过一般手段进行操纵。如何打破光子传输的时间反演对称性，实现适用于片上集成的非互易光学元件一直是集成光电子领域面临的难题。目前打破光传输互易性的方法主要是利用特定材料的磁光效应，通过外加强磁场来实现光学二极管功能。但是磁光响应速度慢，强磁场体积庞大且难以作用到器件的局部区域，因此传统的磁光效应尚无法应用到集成光子芯片。发展新型非磁光学二极管和隔离器，在光学集成领域多年来一直没有实质性突破。

　　中国科学院化学研究所光化学重点实验室研究员赵永生课题组的研究人员在前期研究工作中发现，有机微纳晶体材料在激发状态下所形成的定域在单个分子上的Frenkel激子，相比于无机材料中的Wannier激子，具有更高的结合能和更长的激发态寿命，因此容易与光子耦合，从而形成激子极化激元（Exciton Polariton）（J. Am. Chem. Soc. 2011, 133, 7276-7279；Acc. Chem. Res. 2014, 47, 3448-3458; Angew. Chem. Int. Ed. 2015, 54, 7125-7129）。这是一种半光半物质的新的量子态，兼具光子和激子的属性。虽然光子本身的行为是很难进行人为操纵的，但是激子极化激元的形成，使得人们有可能通过对激子的操纵来间接地操纵光子（J. Am. Chem. Soc. 2012, 134, 2880-2883; Adv. Mater. 2012, 24, 1703-1708; Adv. Mater. 2013,25, 2854-2859; J. Am. Chem. Soc. 2016, 138, 2122-2125; J. Am. Chem. Soc. 2017, 139, 11329-11332.）。Frenkel激子本是可以看作电偶极子，因此外加电场可以引起激子扩散、分离、复合等行为的改变。

　　最近他们与中国科学技术大学，清华大学及美国西北大学的研究人员合作，首次利用静电场对激子扩散行为的影响，在单根有机半导体纳米线中打破了光传输的对称性。他们将单根有机单晶纳米线波导材料置于一个外加电场中，电场与激子偶极相互作用，产生一个额外的作用势能，从而引起激子密度沿电场矢量方向重新分布。其结果是原本向纳米线的两个相反方向上等量对称传输的激子，在电场作用下发生了重新分配，而使得纳米线的两端输出的激子数目不再对等。由于激子与光子处于耦合状态，因此电场的引入可以同时打破光传输的对称性，实现电场控制的光学二极管功能（图1 A,B）。

　　研究发现，这样产生的光二极管效应对电场的响应速度非常快（<3 ns，图1F）。通过改变电场强度，可以对光学二极管行为进行调控；当电场方向发生反转时，不对称性也相应地发生反转。在此基础上，研究人员对有机纳米线光学材料施加一个高频脉冲交流电场，当电场方向发生快速转换时，光子向两边传输的不对称性可以进行快速切换，利用一个控制信号，在纳米线的两端得到相位相反的交变输出信号，从而实现了高频率、快速响应的单刀双掷微纳光开关（图1G）。这是首次在微纳结构中通过外加静电场调控光子行为来实现这一功能，这一结果为实现对光子学功能器件的远程控制，优化集成光子器件结构提供了重要借鉴，相关结果发表于Science Advances 2018, 4, eaap9861。
