Abstract

We report the fast detection of terahertz light generated from an electrically-pump terahertz quantum cascade laser lasing at 4.2 THz by terahertz quantum well photdetector. It is demonstrated that the terahertz quantum well photodetector can extract the terahertz light modulated with frequency as high as 6.2 GHz.
