Controlling two-photon emission from superluminal and accelerating index perturbations

Jamison Sloan et al.

Summary: The article proposes a mechanism for the controlled generation of entangled and squeezed photon pairs using superluminal or accelerating modulations of the refractive index in a medium. By controlling the trajectory of index modulation in the medium, frequency and angle correlations of photon pairs can be achieved. The effects are sensitive to the local density of photonic states and can be strongly enhanced using photonic nanostructures.
