Latest Patents

One of Shalaginov's latest patents is for ultra-wide field-of-view flat optics. This innovation provides wide-angle optical functionality that is beneficial for imaging and image projection devices. Traditionally, achieving wide-angle operation requires a complex assembly of optical elements. However, recent advancements have led to the development of meta-surface lenses or meta-lenses. These ultra-thin planar lenses utilize nanoantennas to control the phase, amplitude, and polarization of light. Shalaginov's meta-lens is capable of diffraction-limited focusing and imaging over an unprecedented angular field of view exceeding 170 degrees. The lens is designed on a one-piece flat substrate, featuring an aperture on one side and a single meta-surface on the other. This meta-surface corrects third-order Seidel aberrations, including coma, astigmatism, and field curvature. The design of the meta-lens is generic, allowing for easy adaptation to various meta-atom geometries and wavelength ranges to meet diverse application demands.

Another notable patent involves optical devices with phase-change materials (PCMs). These reversible materials can be integrated into meta-lenses, wave plates, waveguides, gratings, and other optical components to create active optical devices with controllable characteristics. Local heating can induce solid-state phase changes and significant refractive index changes in the PCMs. These changes can greatly enhance the optical characteristics of the devices. Applications for optical devices with PCMs include imaging, orbital angular momentum control, photonic integrated circuits, optical communication systems, and beam steering.
