Observation of bound states in Lieb photonic lattices
arXiv:1412.4713 · doi:10.1103/PhysRevLett.114.245503
Abstract
We present the first experimental demonstration of a new type of bound states in the continuum, namely, compacton-like linear states in flat bands lattices. To this end, photonic Lieb lattices are employed, which exhibit three tight-binding bands, with one being perfectly flat. Our results could be of great importance for fundamental physics as well as for various applications concerning imaging and data transmission.
