Summary on Grant Application Form
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.
