Research

Main thematics

My research interest is in micro/nano-fabrication, fluidics and optics and in the different ways they may play together. I generally pursue projects in MEMS and more precisely in microfluidics, MOEMS, photonics...

I work within the BioMicroDevices team at the MN2S department of FEMTO-ST Institute and particularly with the clean-room facility of MIMENTO.

The different topics I'm pursuing can be split along:

Diphasic micro-fluidics

droplet/bubble generation, surface tension sensor...

Optical MEMS/MOEMS

vibration/acceleration sensor, optical switch with moving waveguides, tunable photonic crystals...

Thin-film micromachined 3-D mirrors

Micro-optics

refractive microlenses fabrication, microlenses metrology, micro-mirror for optical switch...

Micro/Nano-fabrication technology

one step etch and release DRIE process, nano-patterning techniques, thickness measurement sensor, tissue scaffold microfabrication...
