Primary goal of the R&D presented is creation of semiconductor single-photon detectors.


According to requirements specifications the developed detector must possess the following basic features:

  • detection of single photons at 1550nm wavelength;
  • work under room environmental conditions, without cooling liquids;
  • principal parameters specified below:
