Title: Inske E Bartels: Innovator in Optical Technologies
Introduction
Inske E Bartels is a notable inventor based in Pinneberg, Germany. He has made significant contributions to the field of optical technologies, holding a total of 3 patents. His work focuses on devices that manipulate light, showcasing his expertise in the area of magneto-optical materials.
Latest Patents
One of Bartels' latest patents is a device for rotating the plane of polarization of linearly polarized light. This innovative device features a ball lens made from magnetic crystalline material, which is preferentially magnetized in the direction of light transmission. The design includes two domes of magnetic garnet material, with their basal planes oriented parallel to one another and perpendicular to the direction of light transmission. A spherical member made of optically transparent non-magnetic garnet material is situated between the domes.
Another significant patent is for a planar optical waveguide and the method of manufacturing it. This invention consists of a crystal body with a non-magnetic substrate that has a first magneto-optical layer epitaxially provided on it. A second magneto-optical layer is also epitaxially provided on the first layer, with both layers made from a material based on iron garnet. The second layer has a refractive index that is slightly higher than that of the first layer, enhancing the optical properties of the waveguide.
