Patent ID: 8767290

Claim:
An electrically pumped lateral emission electroluminescent device comprising: a slotted waveguide comprising a top silicon layer having a thickness between 150 nm and 300 nm and a top layer refraction index associated therewith, a bottom silicon layer having a maximum thickness between 150 nm and 300 nm, a bottom layer refraction index associated therewith, and a reduced thickness portion, and a core layer comprising silicon oxide between said top and bottom silicon layers and having a core layer refraction index associated therewith and a thickness less than 70 nm, the core layer refraction index being greater than each of the top and bottom layer refraction indices, at least one portion of said core layer being in a direction of light propagation and being doped with erbium, and comprising silicon nanocrystals, at least one portion of each of said top silicon and bottom silicon layers being electrically conductive and vertically aligned with the at least one portion of the core layer, and the at least one portion of said top silicon layer defining a top electrode of a metal oxide semiconductor (MOS) structure to be coupled to a direct current (DC) electrical source; the reduced thickness portion of said bottom silicon layer extending laterally from said vertically aligned at least one portion of each of said top and bottom silicon layers to define at least one bottom electrode of the MOS structure to be coupled to the DC electrical source.
