Karl Ebeling 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).

  • 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).
    Type: Grant

  • Semiconductor laser with lateral current conduction and method for fabricating the semiconductor laser
    Patent number: 6944199
    Abstract: A semiconductor laser has a semiconductor body with first and second main areas, preferably each provided with a contact area, and also first and second mirror areas. An active layer and a current-carrying layer are formed between the main areas. The current-carrying layer has at least one strip-type resistance region, which runs transversely with respect to the resonator axis and whose sheet resistivity is increased at least in partial regions compared with the regions of the current-carrying layer that adjoin the resistance region.
