A poster at IFCS 2016

You are here


Florent BASSIGNOT, Microfabrication Engineer at FEMTO Engineering, attend May 9th to 12th the 2016 IEE IFCS, International Frequency Control Symposium in New Orleans, USA.

He presents a poster on "New Radio-Frequency resonators based on Periodically Poled Lithium Niobate thin film and ridge structures".

These new resonators are the result of a work on specific developments of clean room technologies conducted in the frame the RACE3 project with FEMTO-ST, supported by the Labex Action.

Developed technologies:

  • Hybrid wafers
  • Ridge structure
  • Poled wafers


  • suitable for mass production,
  • simple to implement,
  • custom-designed.

Opportunities of technological transfer:

  • Photonics: Electric field sensor, second harmonic generation…
  • Space & Telecom: resonators, sensors…
