Observation of quincunx-shaped and dipole-like flatband states in photonic rhombic lattices without band-touching
We demonstrate experimentally the existence of compact localized states (CLSs) in a quasi-one-dimensional photonic rhombic lattice in the presence of two distinct refractive-index gradients (i.e., a driven lattice ribbon) acting as external electric fields. Such a lattice is composed of an array of...
