摘要
目前，近量子极限的太赫兹（THz）外差接收机需冷却至4 K以下温度。我们致力于构建基于半导体的“可调天线耦合子带太赫兹”（TACIT）1–5 THz外差混频器。我们预测，其在晶格温度高于20 K、本振（LO）功率约1 W的条件下工作，可实现几百K的单边带噪声温度与大于10 GHz的中频（IF）带宽。

This paper was published in the Proceedings of the Far-IR, Submm, and mm Detector Technology Workshop, Monterey, CA (2002). The URL for the proceedings no longer exists, so this eprint is submitted here for public access. The eprint is identical to the version published in 2002. One correction is required: in Eq. (4): Gamma/(2*pi), not Gamma*(2*pi), is the HWHM of the intersubband transition
