Terahertz (THz) wave refers to electromagnetic radiation in the frequency interval from O.1 to 10 THz.THz time-domain spectroscopy (THz-TDS) is a powerful techn
Our recent activities related to detectors working on the terahertz frequency bands will be presented.This paper includes the terahertz-quantum well photodetect
Compact and coherent solid-state sources are important key components for various applications of the THz waves.For semiconductor single oscillators, quantum ca
