项目摘要

The terahertz (THz) frequency region within the electromagnetic spectrum, covers a frequency range of about one hundred times that currently occupied by all radio, television, cellular radio, Wi-Fi, radar and other users and has proven and potential applications ranging from molecular spectroscopy through to communications, high resolution imaging (e.g. in the medical and pharmaceutical sectors) and security screening. Yet, the underpinning technology for the generation and detection of radiation in this spectral range remains severely limited, being based principally on Ti:sapphire (femtosecond) pulsed laser and photoconductive detector technology, the THz equivalent of the spark transmitter and coherer receiver for radio signals. The THz frequency range therefore does not benefit from the coherent techniques routinely used at microwave/optical frequencies. Our programme grant will address this. We have recently demonstrated optical communications technology-based techniques for the generation of high spectral purity continuous wave THz signals at UCL, together with state-of-the-art THz quantum cascade laser (QCL) technology at Cambridge/Leeds. We will bring together these internationally-leading researchers to create coherent systems across the entire THz spectrum. These will be exploited both for fundamental science (e.g. the study of nanostructured and mesoscopic electron systems) and for applications including short-range high-data-rate wireless communications, information processing, materials detection and high resolution imaging in three dimensions.
The terahertz (THz) frequency region within the electromagnetic spectrum, covers a frequency range of about one hundred times that currently occupied by all radio, television, cellular radio, Wi-Fi, radar and other users and has proven and potential applications ranging from molecular spectroscopy through to communications, high resolution imaging (e.g. in the medical and pharmaceutical sectors) and security screening.然而,在该光谱范围内生成和检测辐射的基础技术仍然受到严重限制,主要基于Ti:蓝宝石(飞秒)脉冲激光器和光电导电探测器技术,这是无线电信号的Spark Transmitter和Coerher接收器的THZ。因此,THZ频率范围并非从通常在微波/光学频率下使用的相干技术受益。我们的计划赠款将解决这个问题。我们最近展示了基于光学通信的技术技术,用于在UCL以及剑桥/利兹的最新量子量子级联激光器(QCL)技术以及最先进的THZ量子级联激光器(QCL)技术。我们将汇集这些国际领先的研究人员,以在整个THZ范围内创建连贯的系统。这些将被利用用于基础科学(例如纳米结构和介观电子系统的研究),以及在三个维度中的短距离高数据率无线通信,信息处理,材料检测和高分辨率成像的应用。
