Foerster resonance energy transfer rate and local density of optical states are uncorrelated in any dielectric nanophotonic medium [PDF]

open access: yes, 2015
Motivated by the ongoing debate about nanophotonic control of Foerster resonance energy transfer (FRET), notably by the local density of optical states (LDOS), we study an analytic model system wherein a pair of ideal dipole emitters - donor and acceptor

Scanning emitter lifetime imaging microscopy for spontaneous emission control [PDF]

open access: yes, 2011
We report an experimental technique to map and exploit the local density of optical states of arbitrary planar nano-photonic structures. The method relies on positioning a spontaneous emitter attached to a scanning probe deterministically and reversibly ...

Photon Antibunching and Magnetospectroscopy of a Single Fluorine Donor in ZnSe

open access: yes, 2010
We report on the optical investigation of single electron spins bound to fluorine donor impurities in ZnSe. Measurements of photon antibunching establish the presence of single, isolated optical emitters, and magneto-optical studies are consistent with ...
