Latest Patents

One of his latest patents is focused on "Broadband terahertz generation of metamaterials." This invention provides systems and methods to generate single-cycle THz pulses from a few tens of nanometers thin layer of split ring resonators (SRRs) via optical rectification of femtosecond laser pulses. The emitted THz radiation, with a spectrum ranging from about 0.1 to 4 THz, arises exclusively from pumping the magnetic-dipole resonance of SRRs around 200 THz. This resonant enhancement, along with pump polarization dependence and power scaling of the THz emission, underpins the nonlinearity from optically induced circulating currents in SRRs, showcasing a huge effective nonlinear susceptibility of 0.8×10 m/V that far exceeds surface nonlinearities of both thin films and bulk organic/inorganic crystals and sheet nonlinearities of non-centrosymmetric materials such as ZnTe.

Another notable patent is related to "Dispersion management with metamaterials." This invention includes an apparatus, system, and method to counteract group velocity dispersion in fibers or any other propagation of electromagnetic signals at any wavelength (microwave, terahertz, optical, etc.) in any other medium. The dispersion compensation step or device based on dispersion-engineered metamaterials avoids the need for a long section of specialty fiber or the need for Bragg gratings, which often have insertion loss.
