• electron from above the Fermi level (upper level), hence feeding photons back by stimulated emission resonant with the gap mode. The system reflects many essential features of a superluminescent light emitting diode. Keywords: inelastic tunneling; light emitting diode; quantum plasmonics; scanning near

• results demonstrate how optical enhancement inside the plasmonic cavity can be further increased by localization via tunneling through a molecule. We anticipate that stimulated emission from a tunneling junction will advance our fundamental understanding of quantum plasmonics and lead to new analytical
