Title: Innovations by Inventor Stephan Junger
Introduction
Stephan Junger is a notable inventor based in Bubenreuth, Germany. He has made significant contributions to the field of optical technology, holding a total of 5 patents. His work focuses on advanced optical filters and color sensors, showcasing his expertise in nanostructured layers and semiconductor technology.
Latest Patents
One of his latest patents is an optical filter with nanostructured layers and spectral sensors. This invention relates to an optical filter that consists of at least two nanostructured layers, each forming a transmission grating with grating wires that extend parallel to each other. The grating wires of the two transmission gratings intersect and are positioned one on top of the other. An optical polarizer is arranged over the transmission gratings, polarizing incident optical radiation linearly parallel to the grating wires of one of the transmission gratings. This optical filter can be produced as a bandpass filter using standard semiconductor processes without the need for additional layers or modifications.
Another significant patent is for a color sensor with angle-selective structures. This invention involves a color sensor that includes at least one photosensitive element, with a layer stack of dielectric and structured metal layers constructed in front of it. The color sensor features a color filter that filters optical radiation before it reaches the photosensitive surface. An array of angle-selective passageways allows only parts of the optical radiation within a limited angle of incidence range to pass through to the photosensitive surface. This design enables the integration of angle-selective structures in the CMOS layer stack, allowing for the creation of ultra-flat color sensors.
