Coupling Single Defect Emissions From 2-Dimensional Semiconductors into Long-Range Propagating Gap Plasmons in Metal-Insulator-Metal Waveguides

摘要

We demonstrate coupling of single defect emissions from the 2-D transition metal dichalcogenide (TMDC), Tungsten diselenide (WSe2) into propagating surface plasmon modes in lithographically fabricated silver-air-silver, metal-insulator-metal (MIM) waveguides.
