Photonic metasurfaces offer exceptional control over light at the nanoscale, facilitating
applications spanning from biosensing, and nonlinear optics to photocatalysis. Many …

One of the most fundamental and relevant properties of a photonic system is the local
density of optical states (LDOS) as it defines the rate at which an excited emitter dissipates …

This work presents a bulk refractive index sensor based on quasi-bound states in the
continuum (BICs) induced by broken symmetries in metasurfaces. The symmetry is broken …

As artificially engineered subwavelength periodic structures, terahertz (THz) metasurface
devices exhibit an equivalent dielectric constant and dispersion relation akin to those of …

Dual-symmetry breakings including permittivity asymmetry and geometry asymmetry have
been studied in all dielectric split-ring metamaterials supported bound states in the …

Bound states in the continuum (BICs) have attracted much attention in Nanophotonics for
their (formally) infinite Q factors, quasi-BICs (qBICs) being the symmetry-broken version …
