Quantum and Molecular Photonics Laboratory (LPQM)

Research unit


LPQM's themes are orientated towards molecular photonic and non linear optics. It is composed of three teams: The Non linear nanophotonic and biophotonic team mainly studies non linear properties of nanostructures, action potential in artificial neurons and is also interested in digital microfluidics. The 'Components and technologies for the photonic team is interested in components in optical telecommunications, photonic cristals, laser micro-cavities, optofluidic sensors and in mocular engineering. The ultrafast nanophotonics, nanoplasmonics and heat transfer team works on ultrafast plasmonic, heat nano-sources and heat photo-inducted transfers. Because it takes interest in the whole nano-photonic spectrum and owns a lot of equipment, among others the technological platforms of the D'Alembert institut, the laboratory is an interesting partner for possible collaborations.
