Maciej DEMS 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 cavity surface emitting laser cavity with low thermal impedance
    Patent number: 9337615
    Abstract: The present invention concerns new designs of VCLs with high contrast gratings (HCG) combined with diamond layer as a bottom mirror. They can be realized either with a classical V-shaped pumping scenario, or through the introduction of the pumping beam from the bottom direction, through the HCG that can be designed to be transparent at the wavelength of the pumping light. They can also be completed by a HCG combined with diamond layer as top mirror, reflecting the pump diode laser and transparent to the VCL emission in the case the pumped and emitted beams are collinear.
    Type: Grant
