Abstrak

Influencing spectral and directional features of exciton emission characteristics from 2D transition metal dichalcogenides by coupling it to plasmonic nanocavities has emerged as an important prospect in nanophotonics of 2D materials. Herein, the directional photoluminescence emission from a tungsten disulfide (WS2) monolayer sandwiched between a single‐crystalline plasmonic silver nanowire (AgNW) waveguide and a gold (Au) mirror is experimentally studied, thus forming a AgNW–WS2–Au cavity. Using polarization‐resolved Fourier‐plane optical microscopy, the directional emission characteristics from the distal end of the AgNW–WS2–Au cavity are quantified. Given that the geometry simultaneously facilitates local field enhancement and waveguiding capability, its utility in 2D material‐based, on‐chip nanophotonic signal processing is envisaged, including nonlinear and quantum optical regimes.
