Research Interests:

I. Ledoux's current research interest is focused on molecular and supramolecular engineering of molecules and materials for photonic applications, especially multifunctional nanoscale compounds and structures combining NLO and laser properties. She recently reported the evidence of a significant enhancement of the quadratic nonlinear optical properties of molecules grafted on the surface of gold nanoparticles in solution. Another significant achievement is the demonstration of a huge exaltation of quadratic NLO response for photoswitchable molecules. Another of her activities focused on the elaboration of waveguiding polymer devices combining NLO and gain properties in the near infrared using erbium complexes. She reported a positive net gain in single mode erbium-doped polymer waveguides in 2006. She is currently investigating IR gain properties in polymer materials doped with lead chalcogenide quantum dots, NLO responses of rare earth complexes and oxides, and gold nanoparticles
