Suspended Dielectric Mirrors at Deep Subwavelength Scale by Ze Lin Tan, Ken Liu, Wei Xu, Zhi Hong Zhu

“…This kind of mirrors shows many unique properties, e.g., the mirrors become increasingly transparent with diminishing film thickness at nonresonant wavelength; there is a strong evanescent field distribution outside the mirrors; the reflection wavelength is almost independent of the refractive index of the mirror materials, and nearly only depends on the lattice geometry at the deep subwavelength scale; moreover, their quality factor significantly improves, which is important for applications in laser, cavity optomechanics, and cavity quantum electrodynamics.…”
