项目摘要

The discovery that carbon atoms can form molecules with spherical and tubular geometry has provided researchers with a new class of materials with unique properties called carbon nanotubes (CNTs). In particular these CNTs possess remarkable mechanical and electrical properties that have been used to produce ultra-strong fibres and electron sources for displays amongst many other applications. Recently, studies on the optical properties of these materials have shown that they have much to offer in this area as well. These materials exhibit unique absorption and emission properties that can be controlled through changing the diameter of the carbon tubes. They also have significant potential through the use of their so called non-linear optical properties. These properties are generally observed when high light intensities are present and can be used to control and adapt this light. For example it is possible to rapidly switch the light on and off, change the wavelength (colour) of the light and even form a continuum of light from a short pulse using non-linear properties.The aim of this proposal is to develop a new generation of electrophotonic materials by embedding these carbon nanotubes in polymer and chalcogenide glass hosts. Within these CNT-doped hosts waveguides will be formed and their linear and non-linear optical properties studied. We will exploit them to realise highly functional planar lightwave devices . A key point is that this material will be capable of forming both optical as well as thin-film electronic devices using very similar fabrication processes, thereby opening the door towards the low-cost mass manufacture of fully integrated electrophotonic circuits and systems. Such a development would represent a significant advance in this area and allow a new generation of devices and systems to be developed.

碳原子可以形成具有球形和管状几何形状的分子的发现为研究人员提供了一类具有独特性质的新材料，称为碳纳米管（CNT）。特别是，这些CNT具有显著的机械和电气性能，已用于生产超强纤维和电子源，用于显示器以及许多其他应用。最近，对这些材料的光学性质的研究表明，它们在这一领域也有很大的贡献。这些材料具有独特的吸收和发射特性，可以通过改变碳管的直径来控制。它们还通过使用其所谓的非线性光学特性而具有显著的潜力。当存在高光强度时通常观察到这些性质，并且可以用于控制和适应这种光。例如，利用非线性特性，可以快速地开关光，改变光的波长（颜色），甚至可以从短脉冲中形成连续的光。该提案的目的是通过将这些碳纳米管嵌入聚合物和硫属化物玻璃基质中来开发新一代的电光子材料。在这些CNT掺杂的主机波导将形成和他们的线性和非线性光学性能的研究。我们将利用它们来实现高功能的平面光波器件。一个关键点是，这种材料将能够使用非常相似的制造工艺形成光学和薄膜电子器件，从而为完全集成的电子光子电路和系统的低成本大规模制造打开了大门。这种发展将代表这一领域的重大进步，并允许开发新一代设备和系统。
