SUMMARY:Strong Coupling in Organic and Hybrid Semiconductor Microcavities 
 - Prof. David Lidzey (Department of Physics and Astronomy\, The University
  of Sheffield\, UK)
DTSTART:20141028T143000Z

CONTACT:Dr. Stavros Athanasopoulos
DESCRIPTION:I will overview the phenomena of strong exciton-photon couplin
 g in organic semiconductor microcavities. After introducing a simple descr
 iption of strong coupling through the use of a coupled oscillator model\, 
 I will discuss the field of "Organic Polaritonics"\, starting from the fir
 st reported observations to recent observations of polariton lasing. I the
 n review our work in which we have used PL and PLE measurements to underst
 and the mechanisms by which excited molecular states couple to cavity phot
 ons to form polaritons which then undergo radiative and non-radiative deca
 y. Finally\, I will discuss recent experiments in which we have placed two
  different organic dyes in the same strong-coupled cavity and have evidenc
 ed energy transfer between the dyes using a polariton mediated process. \n
