Slow And Stored Light Under Conditions Of Electromagnetically Induced Transparency And Four Wave Mixing In An Atomic Vapor, Nathaniel Blair Phillips

Dissertations, Theses, and Masters Projects

The recent prospect of efficient, reliable, and secure quantum communication relies on the ability to coherently and reversibly map nonclassical states of light onto long-lived atomic states. A promising technique that accomplishes this employs Electromagnetically Induced Transparency (EIT), in which a strong classical control field modifies the optical properties of a weak signal field in such a way that a previously opaque medium becomes transparent to the signal field. The accompanying steep dispersion in the index of refraction allows for pulses of light to be decelerated, then stored as an atomic excitation, and later retrieved as a photonic mode. This …
