Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. While the invention will be described in conjunction with the preferred embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

[0023] The Faraday anomalous dispersion atomic filter (abbreviated as the atomic filter) has the advantages of high transmittance, narrow bandwidth, and high sideband suppression ratio. There are important applications in deep spectroscopy, laser single-mode frequency stabilization, and so on.

[0024] The transmittance of the atomic filter is determined by the number of atoms in a certain volume that participates in the action. For the V-type energy level structure atoms, once another beam of la...

Abstract

The invention discloses an all-optical switch based on a rubidium-atom optical filter and a method thereof. The all-optical switch based on the rubidium-atom optical filter comprises an alkali-metal rubidium-atom glass air chamber with a V-type energy level structure, two Glan-Taylor polarizers with the polarization directions perpendicular to each other and a stable magnetic field source used for generating a magnetic field with uniform intensity for the alkali-metal rubidium-atom glass air chamber, wherein the alkali-metal rubidium-atom glass air chamber, the two polarizers with the polarization directions perpendicular to each other and the stable magnetic field source form a standard atomic optical filter. The all-optical switch based on the rubidium-atom optical filter further comprises a 420 nm laser device serving as a control part of the all-optical switch of the atomic optical filter and a 780 nm laser device serving as a performance testing and application wavelength testing part of the all-optical switch of the rubidium-atom optical filter. The all-optical switch based on the rubidium-atom optical filter has the advantages of being clear in design principle, simple in structure, easy to manufacture, good in switching performance, stable in operation and long in service life.
