Abstract

We present novel PIN photodiode (PD) continuous wave (cw) terahertz (THz) emitters with an increased responsivity and reduced substrate thickness compared to the state-of-the-art. Our improved devices feature up to 4 dB higher output power below 500 GHz with maximum power of -0.53 dBm at 115 GHz and strongly reduced THz absorption of the substrate for frequencies above 3 THz. The latter enables us to measure coherent cw THz spectra with a record bandwidth of 5.5 THz, for the first time, which is 1 THz (22%) more than the state-of-the-art.

带宽大于 5.5 THz 的超宽带 PIN-PD THz 发射器

我们展示了新型 PIN 光电二极管 (PD) 连续波 (cw) 太赫兹 (THz) 发射器，与最先进的器件相比，它的响应率更高，衬底厚度更小。我们改进后的器件在 500 GHz 以下的输出功率提高了 4 dB，在 115 GHz 时的最大功率为 -0.53 dBm，并且在 3 THz 以上频率时，基底的太赫兹吸收大大降低。后者使我们能够测量相干 cw 太赫兹光谱，其带宽首次达到创纪录的 5.5 太赫兹，比最先进水平高出 1 太赫兹（22%）。

期刊介绍： The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
