Ultra-Fast Photodetectors.

在一个需要以越来越快的速率传输数据的世界里，作为系统一部分的设备的速度越来越成为一个关键参数。此外，太赫兹技术和光子学系统的最新发展突出了对带宽远远超过60 GHz的超快速光电探测器的需求，并增加了电力输出能力。在EPSRC PRINCE项目期间，UCL开发的光电探测器展示了超过108 GHz的-3 dB电带宽，具有破纪录的功率处理。它还通过直接电气连接或集成天线实现了破纪录的输出功率，频率范围从100 GHz到1.5 THz，功率输出范围从110 GHz的10 mW到900 GHz的25 uW。本后续计划拟利用这项开创性工作及其附带的知识产权，并将其进行商业开发。这项工作的关键部分之一将是为两个主要应用开发器件的封装：高数据速率光通信和连续波太赫兹信号产生。商业化的潜力将通过使用封装的设备作为原型，由一组子系统制造商进行评估来进行测试，这些制造商是潜在的客户。这项工作还将包括通过问卷调查和与伦敦商学院（London Business School）进行市场范围研究，对进入市场的商业路线和最佳产品供应进行调查。

In a world needing to transmit data at increasing rates the speed of devices that are part of the system becomes more and more a key parameter. Furthermore the recent developments in terahertz technology and photonics systems highlights the need for an ultra-fast photodetector with a bandwidth well beyond 60 GHz and increased electrical power output capability.The photodetector developed at UCL during the EPSRC PRINCE project demonstrated a -3 dB electrical bandwidth of over 108 GHz, with record breaking power handling. It also achieved record breaking output power by direct electrical connection or from an integrated antenna at frequencies ranging from 100 GHz to 1.5 THz, power outputs ranging from 10 mW at 110 GHz to 25 uW at >900 GHz.This Follow-on programme propose to use this pioneering work and its attached intelectual property, and develop it for commercial exploitation. One of the key parts of this work will be to developed the packaging of the device for two main applications that: high data rate optical communication and continuous wave terahertz signal generation. The potential for commercialization will then be tested by using the packaged devices as prototypes for evaluation by a group of subsystem manufacturers, who are potential customers. The work will also include an investigation of the commercial routes to market and optimum product offerings by using questionnaires and doing a market scoping study with the London Business School.
