Title:
ファラデー回転子及び磁気光学素子
Document Type and Number:
Japanese Patent JP7238892
Kind Code:
B2
Abstract:
A Faraday rotator includes a magnetic circuit including first to third magnetic materials each provided with a through hole through which light passes, and a Faraday element disposed in the through hole. When a direction where light passes through the through hole is defined as a direction of an optical axis, the first magnetic material is magnetized in a direction perpendicular to the direction of the optical axis, the second magnetic material is magnetized in a direction parallel to the direction of the optical axis, and the third magnetic material is magnetized in a direction perpendicular to the direction of the optical axis, and a length of the Faraday element along the direction of the optical axis is shorter than a length of the second magnetic material along the direction of the optical axis.
