Title: Norbert Thorweihe: Innovator in Optical Technology
Introduction
Norbert Thorweihe is a notable inventor based in Aachen, Germany. He has made significant contributions to the field of optical technology, particularly with his innovative designs and patents. His work has had a lasting impact on the development of optical isolators.
Latest Patents
Thorweihe holds a patent for a planar optical isolator. This invention relates to a device that incorporates a magneto-optical gyrotropic layer and an anisotropic birefringent layer. The design ensures that the non-reciprocal rotation of polarization of light, known as Faraday rotation, is effectively managed. This results in a TE-mode being guided with low damping while intensively attenuating at least one TM-mode. The isolator achieves a high isolating effect by connecting magneto-optical gyrotropic layers and anisotropic birefringent layers epitaxially. The waveguiding core layer consists of two differently doped rare earth-iron garnet (YIG) layers, which provide distinct specific birefringence.
