  We numerically demonstrate selective near-field localization determined by
the polarization state of a single emitter coupled to plasmonic nano-cluster.
Seven gold nanospheres are carefully arranged such that up to ten polarization
states of the single emitter, including linear, circular, and elliptical
polarizations, can be distinguished via the distinct field localization in four
gaps. The ability to transform polarization state into field spatial
localization may find application for single emitter polarization analysis.
