In our laboratory, we frequently have to detect photons, whether for:

  • Characterize devices or processes designed in the laboratory which themselves emit photons: emission spectrum, quantum efficiency, polarization of emitted photons, etc.
  • Use photons as a characterization probe for:
    • Deposits of thin layers carried out in the laboratory (ellipsometry…)
    • biological tissues (Müller polarimetry…)

We then developed know-how in the field of photo detection which covers a wide spectrum of photo detector type (solid state, vacuum, oragnic detector) and different types of expertise such as:

  • Characterisation of intrinsic properties
  • Characterisation of light properties
  • Development of associated electronics
  • Photodetector implementation technique

For more than 10 years, the laboratory has participated in the NDIP (New Development In Photodetection) conference cycle. This international conference, which takes place every 3 years, brings together physicists, engineers and industrialists from the international community working in the fields of photo-detection with an average of 200 participants.
