Claim of US Patent No. 9,982,850

1. A structure comprising:a semiconductor light emitting device for emitting a first light at a first wavelength;
a wavelength conversion medium arranged to convert at least part of the first light into a second light at a second wavelength; and
a periodic antenna array comprising a plurality of antennas, wherein the periodic antenna array supports surface lattice resonances arising from diffractive coupling of localized surface plasmon resonances in at least one of the antennas;
wherein a distance between the wavelength conversion medium and the periodic antenna array is smaller than the wavelength of the first light or the second light.
