Summer reading

Our last paper published recently in Angewandte Chemie, has been added to our Publications page. We showed direct evidence of non-radiative energy transfer neither of Förster nor of Dexter type, but due to the delocalized and entangled nature of  the hybrid polaritonic states. We have measured energy transfer efficiency close to 37% for donor-acceptor distances over 100nm.

New members in the team

We have the pleasure to welcome two new post-doctoral researchers in our group since the 1st of July : Marcus Seidel and Kalaivanan Nagajaran.

Kalaivanan is coming from Kerala, India, and did his phD in the School of Chemistry of the Indian Institute of Science, Education and Research of Thiruvananthapuram on the “Strategies to Access Triplet Excited State in Core-Twisted Perylenediimides”, under the supervision of Dr. Mahesh Hariharan.

Marcus is coming from Germany and the topic of his phD work was the development of high power femtosecond thin-disk laser, where his research was focused on pulse compression, carrier-envelope-phase stabilization and broadband mid-infrared generation. It has been prepared in the Max-Planck Institute for Quantum Optics in Garching, in the group of Pr. Ferenc Krausz.

Morevover, Ming-Hao Li, who was with us for a Master 2 training, will stay in the lab and continue for a phD as he received a grant from the Ecole Doctorale de Chimie. Congratulations to him !

Another departure

Xiaolan Zhong, who has been working in our group as a postdoc for three years and a half is leaving us this week. She has obtained an assistant professor position at Beihang University in Beijing and we wish her good luck for the future !

See ya James !

James Hutchison, our dear bloody fair dinkum aussie mate, is leaving today for a 18 months secondment in Melbourne University, we wish him good luck there !

ISIS is expanding

A nice picture of all the ISIS members (at least those present this day, February 21) was taken last week in front of the institute. For information, ISIS will expand next year as the works for the building extension just started this month, a nice way to celebrate its 15th birthday !

A nice PRL Editorial to start 2017

As this 2017 year has started in a somehow troubled and strange manner for the world, we hope that things will stabilize in the coming months.  And as all the actions toward a more peaceful world desserve to be highlighted, we wanted to bring to the fore this nice editorial from Pierre Meystre in Physical Review Letters.

Second-Harmonic generation from hybrid states

We just published a new paper in Nano Letters, resulting from  a collaboration with colleagues at IPCMS (Strasbourg), and Radboud University (Nijmegen), about second-harmonic generation boosted by hybrid light-matter states. This effect is induced by the modification of the nonlinear optical (NLO) susceptibility of organic nanofiber crystals placed into optical microcavities. As the system could be even further optimized, in particular by the use of other types of optical resonators, this opens the door to more efficient NLO organic devices. Please find the paper in our publications page !
