Abstract

A light emitting diode includes a square quantum well structure, the quantum well structure including III-V materials. A dielectric layer is formed on the quantum well structure. A plasmonic metal is formed on the dielectric layer and is configured to excite surface plasmons in a waveguide mode that is independent of light wavelength generated by the quantum well structure to generate light.
