Multilayer structure of the emitter/receiver modules.
Photoconductive Switches
Compact modules for pulsed terahertz generation
- Fiber-Coupled InGaAs Antennas
- SM/PM fiber pigtail and Silicon lens included
- High bandwidth > 6 THz, typ. 70 µW power
- Core components of TeraFlash pro and TeraFlash smart
Pulsed terahertz generation with leading-edge technology: InGaAs antennas provide about 30 µW power and a bandwidth of 6 THz. The emitter and detector modules, developed by Fraunhofer Heinrich-Hertz Institute (Berlin/Germany), are packaged with a Silicon lens and SM/PM fiber. A new transceiver combines emitter and receiver in a single housing, enabling reflection measurements at vertical incidence. All devices can be used with TOPTICA’s TeraFlash pro and TeraFlash smart, but are available as individual modules too.
