We report a plasmonic Fabry-Perot (F-P) microcavity with silver nanoparticles and a continuous silver film function as the end mirrors, where the silver nanoparticles were produced through photo-reduction. Filled with a layer of light-emitting polymer, the F-P microcavity becomes an active device with its output spectrum dependent on localized surface plasmon resonance (LSPR) of silver nanoparticles. A phase shift as large as π is resolved in the resonance modes of the F-P microcavity due to the modulation by LSPR. This leads to complementary spectroscopic performance in the output of the plasmonic microcavity with respect to its non-plasmonic counterparts.
