  • Plasmonic component and plasmonic photodetector and method for producing same
    Patent number: 10276734
    Abstract: The present invention relates to plasmonic components, more particularly plasmonic waveguides, and to plasmonic photodetectors that can be used in the field of microoptics and nanooptics, more particularly in highly integrated optical communications systems in the infrared range (IR range) as well as in power engineering, e.g. photovoltaics in the visible range. The present invention also specifies a method for producing a plasmonic component, more particularly for photodetection on the basis of internal photoemission.
    Type: Grant

  • Actuator for an optical-mechanical scanner and a method of using the actuator
    Patent number: 7142341
    Abstract: In an actuator for an optical mechanical scanner comprising a positioning element for an optical mirror wherein the positioning element is an electrically heatable flexible element consisting of a shape memory alloy having a Curie temperature and a transformation temperature, and wherein the flexible element is ferromagnetic when cold and can be bent in a first position by a magnet but is heated to exceed the Curie temperature and the transformation temperature so as to become paramagnetic whereby the flexible element becomes deformed in the opposite direction.
