Interference of Spontaneous Emission of Light from Two Atomic Ensembles
نویسنده
چکیده
We demonstrate interference of spontaneous emission of light from two distant solid-state atomic ensembles, when both ensembles are coherently excited by a common laser source. Owing to a strong collective enhancement of the spontaneous emission, the atoms behave as ideal two-level quantum systems and no which-path information is left in the atomic ensembles after emission of a photon. This allows us to observe a high fringe visibility of 95%. Our experiment clearly demonstrates the coherent nature of spontaneous emission.

Interference of Spontaneous Emission of Light from two Solid-State Atomic Ensembles
We report an interference experiment of spontaneous emission of light from two distant solid-state ensembles of atoms that are coherently excited by a short laser pulse. The ensembles are Erbium ions doped into two LiNbO3 crystals with channel waveguides, which are placed in the two arms of a MachZehnder interferometer. The light that is spontaneously emitted after the excitation pulse shows fi...
متن کاملCoherent Control of Quantum Entropy via Quantum Interference in a Four-Level Atomic System
The time evaluation of quantum entropy in a four-level double- type atomic system is theoretically investigated. Quantum entanglement of the atom and its spontaneous emission fields is then discussed via quantum entropy. It is found that the degree of entanglement can be increased by the quantum interference induced by spontaneous emission. The phase dependence of the atom-field entanglement is...
متن کاملEntanglement of an Atom and Its Spontaneous Emission Fields via Spontaneously Generated Coherence
The entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. The effect of spontaneously generated coherence (SGC) on entanglement between the atom and its spontaneous emission fields is then discussed. We find that in the presence of SGC the entanglement between the atom and its spontaneous emission fields is completely phase dependent, while in absen...
متن کاملCoherent Transport of Single Photon in a Quantum Super-cavity with Mirrors Composed of Λ-Type Three-level Atomic Ensembles
In this paper, we study the coherent transport of single photon in a coupled resonator waveguide (CRW) where two threelevel Λ-type atomic ensembles are embedded in two separate cavities. We show that it is possible to control the photon transmission and reflection coefficients by using classical control fields. In particular, we find that the total photon transmission and reflection are achieva...
متن کاملQuantum interference in optical fields and atomic radiation
We discuss the connection between quantum interference effects in optical beams and radiation fields emitted from atomic systems. We illustrate this connection by a study of the firstand second-order correlation functions of optical fields and atomic dipole moments. We explore the role of correlations between the emitting systems and present examples of practical methods to implement two system...
