Abstract: The present disclosure relates to a method of forming an antenna layer for use in a light emitting device, the method comprising providing a plurality of particles on a support layer so that a space is formed between at least two particles of the plurality of particles, depositing a material so that at least a portion of the material passes through the space between the at least two particles on to the support layer and removing the plurality of particles from the support layer, the portion of the material remaining on the support layer to form at least a part of the antenna layer.

Abstract: A structure for emitting light is provided. The structure comprises an emissive layer (EML) positioned between electrodes. The EML is tuned such that emission of a transverse electric (TE) waveguide mode from the EML is promoted. The structure further comprises an optical component for diffracting the TE waveguide mode to emit light from the structure.
