Patents by Inventor Thomas Knodl

Thomas Knodl 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).

  • Vertical laser diode with means for beam profile forming
    Patent number: 6990127
    Abstract: A vertical laser diode includes a vertical resonator and a device for shaping the beam profile of the laser diode. The shaping device has at least one decoloring absorber. The configuration provide a vertical laser diode structure that permits stable beam profile shaping.

  • Stacked semiconductor laser diode
    Patent number: 6956881
    Abstract: The present invention relates to an arrangement of semiconductor diode lasers stacked on top of one another, which is arranged on a substrate (1). A first diode laser (12) is arranged on the substrate (1), and a second diode laser (13) is arranged on the first diode laser (12). Between the first diode laser (12) and the second diode laser (13) there is a contact layer (6). The contact layer (6) comprises a first conductive layer (18) of a first conduction type and a second conductive layer (20) of a second conduction type and an interlayer (19) which is arranged between the first and second conductive layers (18, 20).
