Tunable THz Photomixer Driver

product imageThe driver offers an ideal laser source for differential frequency generation in the terahertz and the mid-infrared region. It comprises a DFB-LD, a tunable LD, an erbium-doped fiber amplifier, PLC-based combiner and attenuator, and driver electronics. The driver generates 2λ lights with frequency difference of about 2THz at 1550nm region.
The combination of the driver and the UTC-PD based photomixer is powerful and ideal tool for CW terahertz spectroscopy and imaging.


  • DFB-LD and tunable-LD at 1550 nm
  • 2λ output power (CW, Modulated) up to 100mW
  • Difference frequency tuning up to 2THz
  • Frequency accuracy ±1.5GHz ( ±2.5GHz@EOL)
  • Bias supply (CW, modulation) for photomixer and SBD
