The group has an historical activity in the opto-acoustic and microwave-photonic research themes (as well as in their respective modelling activities). Nevertheless, since the early 2010s, the scope of activities has broadened and current ones fall within 5 main themes:

• modelling:
  • integrated optics (for microwave photonics components)
  • opto-acoustics
  • photovoltaics
• acousto-optics components and systems
  •  tunable optical filtering in the optical telecommunication domain (1.55µm)
  • multi-electrode filters for visible and near-infrared hyperspectral imaging
• microwave-photonics components and systems
  •  high modulation speed white LEDs for LiFi
  • electro-optic switches and beam deflectors for high bit rate analogue to digital conversion
• photovoltaics
• • 1^st generation:
    • « bulk Si »: surface texturization and interface materials
  • 2^nd generation: thin films by PVD
    • « full PVD » CIGS cells
    • earth abundant high bandgap materials
  • 3^rd generation:
    • die sensitized flexible solar cells
    • Si-thin film tandem solar cell
• biosensors
  • Surface plasmon resonance applied to biology and phytosanitary domains
