A first-principles formalism that enables the topological characterization of Weyl points in three-dimensional dispersive photonic continua is introduced. The chirality of Weyl points is computed through gap Chern numbers and through direct computation of the Berry curvature, in both cases solely using the photonic Green’s function.
