Open optical cavities based on metasurfaces
WebWhile previous tunable metasurfaces were based mainly on tuning of dielectric permittivity or losses in associated tunable elements, here we propose gain-assisted tunable metasurfaces as optical modulators with high ON–OFF ratio. They consist of a dye-doped film placed within metal-insulator-metal (MIM) cavities. Web20 de set. de 2024 · In this paper, multiple Fano resonances preferred in the refractive index sensing area are achieved based on sub-wavelength metal-insulator-metal (MIM) waveguides. Two slot cavities, which are placed between or above the MIM waveguides, can support the bright modes or the dark modes, respectively. Owing to the mode …
