Atomic guiding of hollow metallic optical fiber and its Monte-Carlo simulation

At first, the distributions of the electromagnetic field and the optical intensity are calculated for the TE₀₁ mode in hollow metallic optical fiber. Then, taking ⁸⁵Rb atom as an example, the optical potential between ⁸⁵Rb atom and TE₀₁ mode is calculated, and the study results show that the TE₀₁ mode is basically distributed in the hollow region of the metallic optical fiber, i.e. it is circularly distributed along the fiber cross section. Finally, the guiding efficiencies of the straight guide and the bent guide in the hollow metallic optical fiber are simulated respectively by Monte-Carlo method, which show that the guiding efficiency by the bent scheme is obviously lower than that by the straight scheme. The characteristics of the bent guiding scheme show that the atomic guiding in hollow metallic optical fiber not only can be used in atom interference, but also can be used as a velocity measurement instrument based on a circular hollow metallic optical fiber.
