Webb22 juli 2024 · We utilize the strong interaction between the surface plasmon polaritons (SPPs) and excitons in the WSe 2 to give a 73 % change in transmission through the device. We demonstrate control of the... WebbHyperbolic phonon polaritons (HPhPs) are hybrid excitations of light and coherent lattice vibrations that exist in strongly optically anisotropic media, including two-dimensional materials (e.g., MoO 3 ). These polaritons propagate through the material’s volume with long lifetimes, enabling novel mid-infrared nanophotonic applications by compressing … how to charge wonderboom 2
