ABSTRACT
Nanoscale photonic devices made of plasmonic structures can control the reflection, transmission, and polarization properties of the electromagnetic field to achieve high-spectral-resolution of light. Here we experimentally demonstrate the use of a real time plasmonic optical filter for photon sorting of fluorescence emission from nanoenvironments in a multispecies system. This was achieved by utilizing surface plasmon-coupled emission associated with nanometer thick metal films for the fluorescence spectral resolution of monomer, dimer, and higher order aggregates of Rhodamine-6G. We highlight the ability to resolve individual emissions from nanostructures in a complex system in its native state without requiring specialized cryogenic and/or high pressure platforms.
