The Quantum and Molecular Photonics Laboratory is a CNRS joint research unit run by INSIS and ENS Paris-Saclay.


The LPQM is headed by Ledoux Rak and has three research teams:

  • Photonics components and technologies
  • Nonlinear nanophotonics and biophotonics
  • Ultrafast nanophotonics, nanoplasmonics and heat transfer


List of the various research themes addressed by the LPQM teams:

  • Applications of nonlinear two-photon microscopy in biology
  • Active and passive components for optical telecommunications and sensors without fluorescent markers and sensors
  • Polymer-based photonic structures and applications
  • Development of new techniques in non-linear microscopy
  • Molecular engineering
  • Organic microlasers
  • Ultrafast photon modulation in a plasmonic cavity
  • Nanoimaging and nanomanufacturing
  • Nano-sources of heat for chemistry and biology
  • Optoelectronic oscillator
  • Nonlinear properties of nanoparticles and isolated nanostructures
  • Thermo-optical properties of nanocomposite media
  • Ultrafast plasmonics in metal nanoparticles
  • Tracking and manipulation of nanoobjects using one-photon fluorescence techniques
  • Photo-induced heat transfer over short time and space scales
  • Towards the detection of action potentials in artificial membranes and neurons
