The WM-20 wavemeter is based on proven technology that makes use of the photonic integrated arrayed waveguide grating (AWG) concept. Using photonic integrated technology an exceptional thermal stability and highly accurate measurements can be achieved. The wide operating wavelength range of 80 nm allows measurement over the entire C-band. Measurement accuracies can be obtained at high speeds of 100 MHz and higher.This speed is one million times faster than wavemeters currently on the market and allows for live monitoring of the laser wavelengths serving a multitude of high end applications.


  • Absolute wavelength accuracy of  0.1 pm
  • Entire C and L band analysis
  • Pulsed and CW lasers
  • Up to 200MHz acquisition speed
  • Wafer based technology


  • Accurate wavelength analysis of single frequency transmitters (DFB lasers and VCSELs)
  • Accurate and fast tunable laser wavelength analysis and calibration
  • Accurate wavelength calibration of optical spectrum analyzers (OSA)
