In one aspect, there is provided an apparatus including a light emitting diode. The apparatus may include a plurality of layers including a substrate layer, a buffer layer disposed on the substrate layer, a charge transport layer, a light emission layer, another charge transport layer, and/or a metamaterial layer. The other charge transport layer may have at least one channel etched into the other charge transport layer leaving a residual thickness of the other charge transport layer between a bottom of the etched channel and the light emission layer. A metamaterial layer may be contained in the at least one channel that is proximate to the residual thickness of the charge transport layer. The metamaterial may include a structure including at least one of a dielectric or a metal. The metamaterial may cause the light emitting diode to operate at higher frequencies and with higher efficiency.
