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. If you are interested in joining us, please contact Prof. Yu-Hsiang Cheng.
