Spatially-Mapped Mobile Terahertz Spectroscopy (T-MAP)

太赫兹频段被广泛认为是最具挑战性和最不发达的频段，因为缺乏有效地连接微波(低于100 GHz)和光学(高于10太赫兹)之间过渡区域的技术。需要一种全新的方法，使现代工业世界能够利用新的应用程序。T-MAP提出将色散光学与先进的半导体技术相结合，实现非相干太赫兹频谱分析仪和非相干光谱仪，打破了经典相干系统设计方法的许多传统权衡。与设计复杂的相干电子系统不同，T-MAP遵循一种新的非相干、空间映射的检测方法，以及一个脉冲源。非相干探测器阵列和色散光学元件将组成分析器部分，而与光源的组合将分析器变成光谱仪。主要目的是分析实现这种系统的基本方法和局限性，以得出未来硅基宽带太赫兹光谱/光谱分析的理论和实验研究。因此，T-MAP将利用最先进的、商业上可用的硅工艺技术。该项目的最终目标是通过应用频谱分辨率权衡，演示覆盖至少十年带宽(0.15-1.5 THz)、信噪比为30分贝的太赫兹频谱分析和光谱分析。将固定的实验室设备转变为移动设备，为太赫兹体制下的新应用奠定了基础。

The terahertz frequency range has been widely considered as the most challenging and under-developed frequency range due to the lack of technologies to effectively bridge the transition region between microwaves (below 100 GHz) and optics (above 10 THz). A fundamentally new approach is needed to enable novel applications to be harnessed by the modern industrial world. T-MAP proposes to combine dispersive optics with advanced semiconductor technologies to realize both an incoherent terahertz spectrum analyzer and an incoherent spectrometer, which breaks many of the traditional trade-offs of classical coherent system design approaches. Instead of designing complex coherent electronic systems, T-MAP follows a novel incoherent, spatially-mapped detection approach, along with a pulsed source. An incoherent detector array and dispersive optics will make up the analyzer part, whereas the combination with the source turns the analyzer into a spectrometer. The main objective is to analyze the fundamental methods and limitations of implementing such systems to derive future theoretical and experimental research towards silicon-based broadband terahertz spectroscopy/spectral analysis. T-MAP, therefore, will exploit state-of-the-art, commercially available silicon process technologies. This project finally aims to demonstrate terahertz spectral analysis and spectroscopy covering at least a decade of bandwidth (0.15-1.5 THz) with an SNR of 30 dB by applying a spectral resolution trade-off. Transforming stationary lab-based equipment into mobile equipment forms the basis for novel applications in the terahertz regime.
