Tunable THz Optoelectronic Tester

高频和通信技术研究所的中心研究重点是电磁频谱的太赫兹部分的发展。为此，新型太赫兹相机，通信和传感器系统的基础上创新的电路概念和光电元件进行了研究。为了表征这些器件，需要并请求基于激光的“宽带THz光电测试仪”。该设备能够产生和检测具有极高光谱纯度和低相位噪声的宽带（0.1 - 2.7 THz）太赫兹信号。此外，可以开发用于780 nm和440 nm波长范围的新的基于SiGe的光电集成器件。“可调谐THz光电测试仪”设备由以下四个部分组成：A）THz发射机（拍频发生器），B）THz光机械，C）THz接收机（拍频发生器），和D）片上THz信号处理器。

The central research focus of the Institute for High Frequency and Communication Technology is the development of the terahertz portion of the electromagnetic spectrum. For this purpose, novel THz cameras, communication and sensor systems are investigated based on innovative circuit concepts and optoelectronic components. To characterize these devices, a laser-based "broadband THz optoelectronic tester" is required and requested. This equipment enables the generation and detection of broadband (0.1 - 2.7 THz) terahertz signals with extreme spectral purity and low phase noise. In addition, new optoelectronic SiGe based integrated devices for the 780nm and 440nm wavelength range can be explored. The "Tunable THz Optoelectronic Tester" equipment consists of the following four components: A) THz transmitter (beat generator), B) THz optomechanics, C) THz receiver (beat generator), and D) On-chip THz signal processor.
