SUMMARY:Optical Control of Molecular Spontaneous Emission
DESCRIPTION:Featuring Mathias Steiner\, Tübingen University\, Germany\n\nP
	art of the Biophysics/Condensed Matter Seminar Series.\n\nPlanar optical mi
	croresonators having a mirror spacing of one half emission wavelength (&lam
	bda;/2) of embedded molecules are unique tools to control the molecular rad
	iative properties and have attracted considerable scientific and technologi
	cal interest. We developed a new microresonator design that allows us to in
	vestigate experimentally the radiative coupling between single molecules an
	d photonic modes of the microresonator. Using confocal optical microscopy a
	nd spectroscopy\, we studied the influence of the microresonator on the spo
	ntaneous emission rate of embedded molecules and the implications on the mi
	croresonator-controlled molecular emission. The experimental findings were 
	compared with results obtained from calculations and computer simulations. 
	We demonstrate that it is possible to optically control the vibrational deg
	rees of freedom of single dye molecules and single-walled carbon nanotubes\
	, respectively\, by coupling the molecular vibrations to photonic modes of 
	the λ/2-microresonator. Our findings enable tailoring advanced light
	 emitting micro-devices as well as sensing applications for (bio-)chemical 
	analysis offering single molecule sensitivity.
