Claim:
1. A light emitting device, comprising: an electrode layer; a first metal layer disposed on the electrode layer and comprising a first metal portion and a second metal portion separated from the first metal portion at a first lateral distance, wherein the first metal portion and the second metal portion have a first period; a second metal layer disposed above the first metal layer; and an organic material layer disposed between the electrode layer and the second metal layer and comprising a first emitting region separating the first metal portion from the second metal portion, wherein the first lateral distance and the first period enable a lateral plasma coupling generated between the first metal portion and the second metal portion, such that light generated by the organic material layer at the first emitting region has a gain in a first waveband, or a peak wavelength of the light generated at the first emitting region shifts to the first waveband.
