Abstract
Official abstract text for this publication.
Provided is a magneto-optic element that enables easy size reduction of an optical isolator. A magneto-optic element is formed of two or more magnetic members joined together.
First claim
Opening claim text (preview).
The invention claimed is: 1. A column-shaped magneto-optic element formed of two or more magnetic members joined together, wherein the two or more magnetic members are two or more glass members that are each column-shaped, the two or more glass members each have a joint surface, and the two or more glass members are fusion-joined to each other along the joint surfaces of the two or more glass members, and the two or more glass members contain, in % by mass, 78% or more Tb 2 O 3 in a composition thereof. 2. The column-shaped magneto-optic element according to claim 1 , being used as a Faraday rotator. 3. The column-shaped magneto-optic element according to claim 1 , wherein the two or more glass members are joined together in tandem along a length direction so that the joint surfaces of the two or more glass members are perpendicular to a direction of travel of laser light. 4. The column-shaped magneto-optic element according to claim 1 , wherein the two or more glass members are joined together in parallel along a length direction so that the joint surfaces of the two or more glass members are parallel to a direction of travel of laser light. 5. The column-shaped magneto-optic element according to claim 1 , wherein the two or more glass members have a cylindrical shape.
