• [2] Dark light als Licht bei vollständig destruktiver Intereferenz: "Dark light is produced when two or more beams of light interfere destructively and cancel each other out to form a spot that appears completely black to the human eye. […] Because the vortices are regions of zero light intensity, the chromatic effects predicted by theory are extremely subtle." In: Isabelle Dumé: Optical vortices show their true colours.

• [3] Dark light in Analogie zu Kaustik: "Wave optics, when represented by complex scalar wavefunctions, introduces the additional concept of phase, which has its own singularities. Equivalent terms for phase singularities are optical vortices, nodal manifolds or wavefront dislocations28,29. On phase singularities, the light intensity is zero, so these are the singularities of dark light. […] Phase singularities are complementary to caustics, not only because the former are dark (zero intensity) and the latter are bright (infinite intensity), but also in the sense of Niels Bohr: caustics are prominent features in the short-wave asymptotic regime, in which phase singularities are too close to be clearly resolved […]" In: Berry, M.V.
