Abstract

We have observed enhancement of fluorescent emissions from two optically trapped microparticles as the interparticle separation is decreased. Dye-doped latex particles with 1-μm diameters are used as the microparticles. These particles are positioned using twin laser tweezers and are pumped by a frequency-doubled Nd:YAG laser. The measured values are compared with theoretical estimates for the case of an excited atom interacting with its image in the vicinity of a dielectric surface, and the enhancement is attributed to the dipole-dipole interaction modifying the transition rates of the two radiating dipoles.
