  • Collimating metalenses and technologies incorporating the same
    Patent number: 10132465
    Abstract: Metalenses and technologies incorporating the same are disclosed. In some embodiments, the metalenses are in the form of a hybrid multiregion collimating metalens that includes a first region and a second region, wherein the hybrid multiregion collimating metalens is configured to collimate (e.g., visible) light incident thereon. In some instances the first region includes an array of first unit cells that contain subwavelength spaced nanostructures, such that the first region functions as a subwavelength high contrast grating (SWHCG), whereas the second region includes an array of second unit cell, wherein the array of second unit cells includes a near periodic annular arrangement of nanostructures such that the second region approximates the functionality of a locally periodic radial diffraction grating. Lighting devices including such metalenses are also disclosed.
