Photonic Weyl point in a two-dimensional resonator lattice with a synthetic frequency dimension
Abstract
Weyl points, point degeneracies surrounded by linear dispersions, are the 3-dimensional analogue of the Dirac points known from 2D materials. Here, Linet al. propose a scheme for realizing on-chip electromagnetic Weyl points by utilizing the concept of synthetic dimensions.
