Schottky Receivers
Versatile equipment for terahertz sensing
- Zero-bias Schottky diodes
- Output signal proportional to incident terahertz power
- Ideally suited for terahertz imaging
- Compatible with emitters of TeraScan 780 and TeraScan 1550
Schottky diodes work as incoherent receivers (i.e., power detectors) of terahertz radiation. The output signal is phase-insensitive and does not depend on the terahertz path length or sample thickness. Terahertz imaging thus benefits from both speed and sensitivity of the Schottky receivers.
