title: Detection of plasmon-enhanced luminescence fields from an optically manipulated pair of partially metal covered dielectric spheres.
abstract: Using optical tweezers combined with luminescence measurements we detected the optical field around two optically trapped silica microspheres partially covered by metal. By monitoring the luminescence of rhodamine 6G we were able to observe an increase of the local field intensity owing to the coupling of the local surface plasmons at the surfaces of two spheres.
