Patents by Inventor Mark Kenneth Jablonski

Mark Kenneth Jablonski 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).

  • Optical pulse lasers
    Patent number: 7372880
    Abstract: The present invention provides pulsed lasers which employ carbon nanotubes, particularly layers of carbon nanotubes, as saturable absorbers, mode lockers or for Q-switching elements. The present invention also provides methods and materials for mode-locking and Q-switching of lasers in which carbon nanotubes are employed as non-linear optical materials and/or saturable absorbers which facilitate mode-locking and/or Q-switching. The invention further provides mode locker and Q-switching elements or devices which comprise one or more layers containing carbon nanotubes which layer or layers function for mode locking and/or Q-switching.

  • Completely thin-film based optical dispersion compensating element
    Publication number: 20020064334
    Abstract: A completely thin-film coupled three-cavity dispersion compensation element enables dispersion compensation over wider bandwidths then similar elements having fewer coupled cavities. By cascading these dispersion compensation elements even greater compensation bandwidths can be obtained, thereby further increasing the merit and usefulness of this device.
