Herbert Munder has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5831329
    Abstract: An electronic component has electrically activatable layer, e.g. in electroluminescent layer of porous silicon on a body of which two multiarthogonal grids are buried. A conductive layer on the electrically activatable layer forms a drain and another conductor forms the source, the grid bars being independently energizable to form current channels through the electrically activatable layer.

  • Patent number: 5696629
    Abstract: The invention relates to an optical component consisting of transparent thin layers of differing thickness and refractive indices. Such optical components are used, for example, as interference filters and mirrors. Optical components made of layers with gradually changing refractive indices are also known as waveguides of anti-reflective coatings. The invention achieves the aim of using, instead of layers of ordinary materials, another material by means of a component in which the layers consist of porous silicon. The special advantages of porous silicon as a coating material arises not only from the ease and economy of manufacture, but also in the facility for obtaining gradual refractive index transitions. It is therefore very easily possible to make waveguides on a silicon chip.
