As a consequence of the strong many-body interactions in the electron-hole plasma, a semiconductor laser efficiently interacts with terahertz radiation. The injection of terahertz laser radiation into the active region of a diode laser induces a measurable variation of the voltage over the p-n junction, indicating the potential of a semiconductor laser to act as a terahertz detector.
