|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.|
