Title: Innovations of Hans-Jurgen Schmitt
Introduction
Hans-Jurgen Schmitt is a notable inventor based in Aachen, Germany. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on the development of advanced optical isolators and waveguide devices.
Latest Patents
One of his latest patents is a planar optical isolator. This invention relates to a planar optical isolator that features a magneto-optical gyrotropic layer and an anisotropic birefringent layer. These layers are proportioned to ensure that the non-reciprocal rotation of polarization of light, resulting from the action of a magnetic field, is effectively managed. This design allows for low damping of the TE-mode in the forward direction while intensively attenuating at least one TM-mode. Another significant patent is a non-reciprocal optical waveguide device, particularly useful as an isolator or circulator. This device connects to at least two monomode optical waveguides and incorporates a magneto-optical waveguide structure subjected to a transversal magnetic field. The arrangement simplifies the functions of the coupler and phase shifter, enhancing the overall efficiency of the device.
