Thématique “Optofluidique”

About the Optoflow group :

       

  

Optofluidics refers to the microfluidic area where optics and fluids are coupled together to create optical functions in fluids or conversely, to actuate fluids at a micrometric scale with optics. The LOMA optofluidic group aims at investigating these couplings with liquids and liquid interfaces and their consequences when photons exchange momentum and transfer energy.

To investigate these effects, we build setups dedicated to the optomechanics of liquid interfaces (radiation pressure) and bulk (scattering forces), optical stretching, jet instability, liquid fibre stabilization, liquid lenses and optical fountains. We also applied these concepts to optorheology, i.e. the characterization of the rheology of complex fluids at small scale. Fluid flows induced by laser heating in bulk (thermoconvection) and at interfaces (thermocapillarity flows) are also investigated with applications going from laser microfluidics & digital optofluidics to laser-driven evaporation & surface patterning.
