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.

太赫兹频率范围被广泛认为是最具挑战性和开发不足的频率范围，因为缺乏有效桥接微波（低于100 GHz）和光学（高于10 THz）之间过渡区域的技术。 需要一种全新的方法来使新的应用程序能够被现代工业世界所利用。T-MAP提出将联合收割机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，这打破了经典相干系统设计方法的许多传统权衡。T-MAP没有设计复杂的相干电子系统，而是遵循一种新颖的非相干、空间映射的检测方法，沿着脉冲源。非相干探测器阵列和色散光学器件将组成分析仪部分，而与源的组合将分析仪变成光谱仪。主要目的是分析实现这种系统的基本方法和局限性，以获得未来的理论和实验研究对硅基宽带太赫兹光谱/光谱分析。因此，T-MAP将利用最先进的商业化硅工艺技术。该项目的最终目标是通过应用光谱分辨率权衡来展示太赫兹光谱分析和光谱学，其覆盖至少十年的带宽（0.15-1.5 THz），SNR为30 dB。将固定的实验室设备转换为移动的设备是太赫兹领域新应用的基础。
