Embodiment Construction

[0016] see figure 1 , the present invention utilizes the characteristics of the Faraday effect related to the direction of the magnetic field and the direction of light wave transmission, and places a cylindrical magneto-optical glass body 4 in the magnetic field generated by the uniform magnetic field generator 1 to make the direction of the uniform magnetic field generated by the uniform magnetic field generator 1 It 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 is made of an optical material whose magneto-optical rotation coefficient is very small and whose refractive index matches the above-mentioned magneto-optical glass body at a specified wavelength. The number of lenses is two, and the spherical surfaces of the two lenses 2 and 3 are concentrically attached to the two ends of the magneto-optical glass body, so that the ...

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...
