Abdelghani Laraoui 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).

  • Patent number: 10725135
    Abstract: A method of inducing spin polarization in an analyte is provided. The method exposes 14N spin defect centers embedded within 25 nm of a diamond surface to a magnetic field while an analyte is near the surface. The 14N spin defect centers are polarized by treatment with an electromagnetic wave protocol having a visible light pulse (p0); a microwave pulse (mw1), a radio frequency pulse (rf1), a microwave pulse (mw2) and a radio frequency pulse (rf2) resulting in polarization of the nuclear spins of the 14N spin defect centers. Polarized spins in the 14N spin defect centers induce spin polarization in the analyte.

  • Publication number: 20160161583
    Abstract: A method of dynamically polarizing the nuclear spin host of nitrogen-vacancy (NV) centers in diamond is provided. The method uses optical, microwave and radio-frequency pulses to recursively transfer spin polarization from the NV electronic spin. Nitrogen nuclear spin initialization approaching 80% at room temperature is demonstrated both in ensemble and single NV centers without relying on level anti-crossings. This makes the method applicable at arbitrary magnetic fields.
