Title:	Efficient spectroscopy of single embedded emitters using optical fiber taper waveguides
Published:	June 09, 2009
Abstract:	A technique based on using optical fiber taper waveguides for probing single emitters embedded in thin dielectric membranes is assessed through numerical simulations. For an appropriate membrane geometry, photoluminescence collection e?ciencies in excess of 10 % are predicted, exceeding the effciency of standard free-space collec- tion by an order of magnitude. Our results indicate that these tapered fiber waveguides offer excellent prospects for performing effcient spec- troscopy of single emitters embedded in solid-state thin films, such as a single self-assembled quantum dot in a semiconductor membrane.
