NTU THz optoelectronics group

We are interested in all sorts of terahertz (THz) science and technology. Terahertz waves can be applied to fundamental science study, nondestructive imaging, chemical sensing, communication, etc. Our group studies THz waves and their applications with two different approaches: the photonic approach and the electronic approach. For THz photonics, we generate terahertz pulses using femtosecond lasers and apply them to spectroscopy and imaging. For THz electronics, we design and fabricate passive components such as antennas, filters, and waveguides for high-speed communications. For more information, please check our research page.

  • Group meeting: every Wednesday at 3:00 pm

  • Student office: Room 527, EE Building 2

  • Laboratory: Room 527-2, EE Building 2



For the photonics subgroup, students should take 暑期新生訓練 offered by Prof. Wang. (url)
For the electronics subgroup, students should join 夏季電磁教育引領研討會. Check the website of 台灣電磁產學聯盟. (url)


We are looking for graduate and undergraduate students. Students with physics or optics background are mostly welcomed. If you are interested in joining us, please contact Prof. Yu-Hsiang Cheng.
