Title: Helmut Hanisch: Innovator in Optical Technologies
Introduction
Helmut Hanisch is a notable inventor based in Nurtingen, Germany. He has made significant contributions to the field of optical technologies, holding a total of 3 patents. His work has advanced the understanding and application of electrooptical effects in various devices.
Latest Patents
One of Hanisch's latest patents is an optical modulator. This device features a slit arrangement and an associated zone that exhibits both an electrooptical effect and an intrinsic polarization direction. The optical modulator includes an electrode arrangement to which an information signal is applied during operation. The slit arrangement is designed as a double slit arrangement, with three electrodes positioned between the slits. At one slit, the electrical field of the signal aligns with the intrinsic polarization direction, while at the other slit, it is oriented in the opposite direction.
Another significant patent is for an integrated optical waveguide. In this invention, a transparent substrate is covered with a metal layer that serves as an etch mask for forming a groove. This groove leads to the formation of regions that constitute electrodes. The groove and adjacent areas of the substrate are then covered with a layer of material possessing electrooptical properties, with the material in the groove forming an optical waveguide.
