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. 30 µW power
  • New: Transceiver for vertical-incidence reflection measurements
  • 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.
