Nonlinear Optical Detection of Terahertz-Wave Radiation from Resonant Tunneling Diodes
Scientists at Tokyo Tech and RIKEN Center for Advanced Photonics have introduced an optical detection technique for compact electronic terahertz (THz)-wave sources. By incorporating a resonant tunneling diode (RTD), a wavelength from a THz wave can be converted to a near-infrared (NIR) wave that can be detected using a commercial photodetector. The scientists report this technique will open up new opportunities in THz-wave applications.
