OPTICAL ISOLATOR

PROBLEM TO BE SOLVED: To provide an optical isolator and its manufacturing method improved in quality and production yield and excellent in mass productivity, by realizing a manufacturing method to cut out the optical isolators from the state that optical isolator elements and permanent magnets are integrated. SOLUTION: The optical isolator is built by securing an optical isolator element made by stacking at least one or more Faraday rotors and at least two or more polarizers on a stacked magnet made by stacking one of glass, or metal, or ceramic materials, and a permanent magnet.
