碳纳米管作为一种新型的非线性光学器件材料而受到人们的广泛关注。它们的准一维结构提供了它们独特的非线性特性。然而，它们的缺点之一是处理方法。我们已经提出并证明了光学操纵碳纳米管存款他们的核心光纤端部与一个简单的技术。虽然该方法非常简单，但它需要精确控制光功率。该方法不影响CNT层性质的可控性。在本文中，我们采用光学反射测量来解决这些问题。一个15 μ m直径的圆形区域的面积选择性地涂覆使用高度均匀的解决方案的碳纳米管。利用场发射扫描电子显微镜（FE-SEM）首次直接观察了优先沉积的碳纳米管。(C)2009年美国光学学会
Carbon nanotubes (CNTs) emerged as an attractive material for nonlinear optical devices. Their quasi-one-dimensional structure provided their unique nonlinear characteristics. However, one of their drawbacks is the handling method. We have proposed and demonstrated optical manipulation of CNTs to deposit them onto cores of optical fiber ends with a simple technique. Although the method is very simple, it requires precise control of the optical power. The method does not posses controllability of the CNT-layer properties. In this paper, we employed optical reflectometry to solve these problems. A 15 mu m diameter circular region was area-selectively coated by CNTs using highly uniform solution. The preferentially-deposited CNTs were directly, for the first time, observed by a field emission scanning electron microscope (FE-SEM). (C) 2009 Optical Society of America
