Major Detect Devices

Si APDs 

The avalanche effect of Si APDs makes it ideal for detecting weak optical signals with a wavelength from 250 to 1100nm.

 

InGaAs APD 

InGaAs avalanche photodiodes are used to detect signals in the 1100 ~ 1700 nm spectral range. Its noise is lower than that of the germanium diode and is an alternative choice of Si APDs.

Applications

 

  • Quantum Communication

  • Medical Imaging Research

  • Lidar

  • Astronomy

  • Automatic Driving

  • Satellite Remote Sensing

  • Spectroscopy

  • Non-contact Temperature Testing

  • Spectrophotometry

Both two types of our C-band Erbium-Doped Fiber Amplifiers (EDFA) are used to amplify multiple wavelength signals in the C-band. The gain flattening and the conventional type has less than 1dB and less than 3.5 dB gain flatness in the C-band respectively. The amplifier has high stability of optical power output and can be easily tuned to have customized gain through user interface.
