Cw-terahertz spectrum of air with water vapor lines, recorded with a GaAs
photomixer-emitter and a Schottky receiver.
Schottky Receivers
Versatile equipment for terahertz sensing
- Zero-bias Schottky diodes
- Output signal proportional to incident terahertz power
- Ideally suited for terahertz imaging
- Two versions: High Responsivity / High Bandwidth
- Ultrafast version measures individual terahertz pulses
Schottky diodes work as incoherent receivers (i.e., power detectors) for both pulsed and cw-terahertz radiation. Applications like terahertz imaging benefit from both speed and sensitivity of the Schottky receivers. A special high-bandwidth version lends itself for the study of ultrafast processes – owing to its capability of resolving the amplitudes of individual terahertz pulses, even at typical repetition rates of femtosecond fiber lasers!
