Embodiment Construction

[0016] Referring to Fig. 1, the present invention has utilized Faraday effect and the characteristic relevant to magnetic field direction and light wave transmission direction, a columnar magneto-optical glass body 4 is placed in the magnetic field that uniform magnetic field generator 1 produces, the uniform magnetic field that uniform magnetic field generator 1 produces The direction of the magnetic field is perpendicular to the two ends of the magneto-optical glass body 4, so that the magneto-optic glass body is placed in the magnetic field in the same light wave direction as the magnetic field, and an optical fiber with a very small magneto-optical rotation coefficient and a refractive index matching the above-mentioned magneto-optical glass body at a specified wavelength is used. The lens is made of material, and the number of lenses is two. The spherical surfaces of the two lenses 2 and 3 are concentrically attached to the two ends of the magneto-optical glass body, so tha...

Abstract

A magnetooptical component of spherical wave consists of magnetooptical glass body, lens and uniform magnetic field generator which are prepared by magnetooptical material. It is featured as setting magnetooptical glass body in magnetic field generated by uniform magnetic field generator, making end surface of said glass body to be planar form and sticking lens on end surface of it.

Description

1. Technical field [0001] The invention relates to a spherical wave magneto-optical device. 2. Background technology [0002] In the field of optics, the principle of quantitatively changing the polarization direction of polarized light waves by using the optical rotation properties of magnetic optically active materials has been applied to important optical components such as optical isolators. Since the Faraday effect is related to the direction of the magnetic field and the direction of light wave transmission, so Practical similar devices are mostly used in the isolation and polarization rotation of plane light waves, but the optical rotation devices for spherical wave isolation and polarization rotation have not been reported yet. 3. Contents of the invention [0003] The invention solves the technical problem in the background art that there is no optical rotation device for isolation and polarization rotation of spherical waves. [0004] The technical solution of t...
