Abstract
There is provided an illumination device () comprising an energy source () for exciting a photon emitter; a first wavelength conversion layer () and a second wavelength conversion layer (). At least one of the first and second wavelength conversion layer comprises a periodic plasmonic antenna array comprising a plurality of individual antenna elements (). The wavelength converting medium in the wavelength conversion layer in which the antenna array is arranged comprises photon emitters arranged in close proximity of the plasmonic antenna array such that at least a portion of photons emitted from the wavelength conversion layer are emitted by a coupled system comprising the photon emitter and the plasmonic antenna array. The plasmonic antenna array is configured to support plasmonic-photonic lattice resonances at a frequency range corresponding to the wavelength range of the photon emitter in the layer in which the plasmonic antenna array is arranged, such that light emitted from the plasmonic antenna array has an anisotropic angle distribution.
