Keith Russ 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).

  • Free-space, twisted light optical communication system
    Patent number: 10826607
    Abstract: Aspects of the subject disclosure may include, determining a twist number based on digital input data, wherein the twist number corresponds to a predetermined orbital angular momentum of a photon. Orbital angular momentum modulators adapted to change orbital angular momenta of an input signal are adjusted according to the twist number. Application of the input signal to the orbital angular momentum modulators applies orbital angular momenta to the input signal resulting in a twisted light signal having a predetermined number of twists based on the predetermined orbital angular momentum. Other embodiments are disclosed.

  • Free-space, twisted light optical communication system
    Patent number: 10581522
    Abstract: Aspects of the subject disclosure may include, determining a twist number based on digital input data, wherein the twist number corresponds to a predetermined orbital angular momentum of a photon. An adjustment value is generated based on the twist number, and multiple orbital angular momentum modulators are adjusted, wherein the modulators are adapted to change orbital angular momenta of photons of an input optical beam according to the adjustment value. Application of a light beam to the multiple orbital angular momentum modulators applies orbital angular momenta to the input optical beam resulting in a modulated optical beam having a predetermined number of twists based on the predetermined orbital angular momentum. Other embodiments are disclosed.
