Query: Enhanced light emission from gap plasmons in nano-strip MIM tunnel
  junctions   Electrical excitation of light using inelastic electron tunneling is a
promising approach for the realization of ultra-compact on-chip optical sources
with high modulation bandwidth. However, the practical implementation of these
nanoscale light sources presents a challenge due to the low electron-to-photon
transduction efficiencies. Here, we investigate designs for the enhancement of
light generation and out-coupling in a periodic Ag-SiO2-Ag tunnel junction due
to inelastic electron tunneling. The structure presents a unique advantage of a
simple fabrication procedure as compared to the other reported structures. By
efficiently coupling the gap plasmon mode and the lattice resonance, we achieve
a resonant enhancement in the local density of optical states up to three
orders of magnitude and enhanced radiative efficiency of ~0.53, 30% higher as
compared to the uncoupled structure.
