Quantum Interference between Virtual and Real Photons of the Spontaneous Emission in an Atom Embedded in Photonic Band Gap Structure

Zheng Liu

The spontaneous emission is studied with non rotating wave approximation in a three level atom embedded in a photonic band gap structure (PBGS). And the edge of the gap is not located at the center of the two upper levels. Intense quantum interference occurs between the virtual and real photons with a set of suitable parameters. A new localized field is found in the spontaneous emission field, while the atom is partly trapped in the upper levels.

Quantum Interference Effects in Spontaneous Emission from an Atom Embedded in a Photonic Band Gap Structure

Shi-Yao Zhu, Hong Chen, Hu Huang

The spontaneous emission from a three-level atom embedded in a photonic band gap structure is studied. Interference between two transitions leads to quasiperiodic oscillations of population between the two upper levels with large amplitudes. The spontaneous emission of the atom is characterized by three components in the radiated field: a localized part, a traveling pulse, and a $(1/\sqrt{t}{)}^{3}$ decaying part. An analytical expression for the localization distance of the localized field is obtained. The energy velocity for the traveling pulse could be close to zero. By selecting an appropriate initial superposition state, a large amount of population trapping can be achieved.

The spontaneous emission from a three-level atom embedded in a photonic band gap structure is studied. Interference between two transitions leads to quasiperiodic oscillations of population between the two upper levels with large amplitudes. The spontaneous emission of the atom is characterized by three components in the radiated field: a localized part, a traveling pulse, and a (1/t)3(1/\sqrt{t}{)}^{3}(1/t​)3 decaying part. An analytical expression for the localization distance of the localized field is obtained. The energy velocity for the traveling pulse could be close to zero. By selecting an appropriate initial superposition state, a large amount of population trapping can be achieved.
