项目摘要

Miniaturization of optical components for on-chip integration of electronic and photonic functionalities is one of the new frontiers with the promise of enabling a next generation of integrated optoelectronic circuits. A particularly fascinating prospect is the achievement of an optical analogue of the electronic transistor, which forms the building block of our computers. Our approach involves a nanoscale version of a radiowave antenna, the plasmonic nanoantenna. Plasmonic antennas are designed to overcome the diffraction limit of light and to focus light into a nanometer-sized antenna 'feed' gap. In our first studies supported by EPSRC we have proposed a variety of devices exploiting hybrid interactions of a nanoantenna with an active substrate. Here, we aim to launch a full-scale investigation of such hybrid antenna devices including various geometries and metal oxide substrates, where the plasmonic antenna will be exploited as a nanoscale sensitizer for the active substrate. Integration of a nanoantenna switches with a nanoelectronic transistor will yield a new class of optoelectronic devices: the nanoantenna MOSFET.The proposed optically and electrically controlled nanoantenna devices are of enormous interest as a bridge for on-chip control of electrical and optical information. In addition, ultrafast active control of local fields and antenna radiation patterns will enable new applications in nonlinear optics, Raman sensors, and optical quantum information technology.

用于电子和光子功能的片上集成的光学部件的小型化是新的前沿领域之一，有望实现下一代集成光电电路。一个特别令人着迷的前景是电子晶体管的光学模拟的实现，它构成了我们计算机的基石。我们的方法涉及一个纳米级版本的无线电波天线，等离子体纳米天线。等离子体天线被设计成克服光的衍射极限，并将光聚焦到纳米尺寸的天线“馈电”间隙中。在EPSRC支持的第一项研究中，我们提出了利用纳米天线与有源衬底的混合相互作用的各种设备。在这里，我们的目标是启动一个全面的调查，这种混合天线设备，包括各种几何形状和金属氧化物基板，其中的等离子体天线将被利用作为纳米级敏化剂的活性基板。纳米天线开关与纳米晶体管的集成将产生一种新型的光电器件：纳米天线MOSFET，这种光电控制的纳米天线器件作为片上控制光电信息的桥梁，具有巨大的应用前景。此外，局部场和天线辐射模式的超快主动控制将使非线性光学、拉曼传感器和光量子信息技术的新应用成为可能。
