30 多年前构思的光电导 (PC) 发射器已被证明对于太赫兹技术的开发和传播至关重要。从那时起，它们不仅被广泛用于各种光谱和成像应用，而且性能也得到了显着改进，从而可用于宽带或非线性光谱。在这篇评论文章中，我们对文献进行了概述，重点介绍了 PC 发射器发展过程中的关键里程碑。我们还调查了 PC 技术的未来并回顾了现有的挑战。
Conceived over 30 years ago, photoconductive (PC) emitters have proved essential in the development and spread of terahertz technology. Since then, not only have they been used extensively in a wide range of spectroscopic and imaging applications, they have also undergone significant improvements in performance, leading to their use for broadband or non-linear spectroscopy. In this review article, we provide an overview of the literature, highlighting the key milestones in the progression of the PC emitter. We also investigate the future of PC technology and review the existing challenges.
