The method for manufacturing the integrated optical isolator with multimode interference section using magneto-optic effect

摘要

The present invention relates to a method for producing integrated optical isolator having a multi-mode interference region with a magnetic optical effect that, in particular, to applying a magnetic field to the 1 1 region causing a single multi-mode multi-mode interference relates to a method of manufacturing an optical isolator of changing the effective refractive index. ; Using the magnetic optical effect of the present invention The method for producing integrated optical isolator having a multi-mode interference region is the light traveling in the light traveling in the front and rear added to the external magnetic field in a direction parallel to the vertical plane while the optical waveguide in the direction of movement of the light on each of the multi-mode waveguide region includes a different effective refractive index (effective refractive index) of optical isolator integrated production process having a multi-mode interference region with a magnetic optical effect to have.
