Electromagnetically induced transparency
... The concept of EIT was first given by Harris et al in 1990. When a strong coupling laser field is used to drive a resonant transition in a three-level atomic system, the absorption of a weak probe laser field can be reduced or eliminated provided the two resonant transitions are coherently coupled t ...

... The classical (Rayleigh-Jeans) theory works okay for longer wavelengths but predicts that the intensity should continue to increase as the wavelength decreases. Planck assumed that an atom oscillating at frequency f can only have certain energies given by E = nhf. He quantized the energy of an atom, ...

In this paper we investigate a one-photon field that is the result of spontaneous emission; this field state is a linear combination of many singly-occupied field modes. The classical phase and amplitude informatio ...
