Emerging Terahertz Integrated Systems in Silicon

Silicon-based terahertz (THz) integrated circuits (ICs) have made rapid progress over the past decade. The demonstrated basic component performance, as well maturity of design tools and methodologies, it possible to build high-complexity THz systems. Such implementations are undoubtedly highly attractive due their low cost high integration capability; however, unique characteristics, both advantageous disadvantageous, also call for research investigations into unconventional systematic architectures novel applications. In this paper, we review current status future trend silicon-based ICs, with focus on state-of-the-art microsystems emerging sensing communication applications in last few years, such high-resolution imaging, medium/long-term stability time keeping, high-speed wireline/wireless communications, miniaturization RF tags, packaging technologies.
