    "abstract": "We demonstrate that Aharonov-Albert-Vaidman (AAV) weak values have a direct\nrelationship with the response function of a system, and have a much wider\nrange of applicability in both the classical and quantum domains than\npreviously thought. Using this idea, we have built an optical system, based on\na birefringent photonic crystal, with an infinite number of weak values. In\nthis system, the propagation speed of a polarized light pulse displays both\nsuperluminal and slow light behavior with a sharp transition between the two\nregimes. We show that this system\u0027s response possesses two-dimensional,\nvortex-antivortex phase singularities. Important consequences for optical\nsignal processing are discussed.",
