Apparatus for generating THz (terahertz) radiation, the apparatus comprising: a substrate; a planar array of subwavelength antennas formed on the substrate having rotational symmetry, Cn, of order 'n' greater than or equal to 3 and rotational symmetry cycle 2π/η, which are excitable by near infrared (NIR)_pump radiation to radiate THz radiation having wavelengths that are substantially larger than characteristic dimensions of the subwavelength antenna; wherein the array comprises a plurality of sections each comprising plurality of subwavelength antennas exhibiting a spatial pattern different from that of an adjacent section of the plurality of sections.

Methods for generating and controlling terahertz radiation

An optical system for a see-through display includes a stack of metasurface layers configured to receive light constituting an image; and a waveguide coupled to the stack. Each layer in the stack of metasurface layers is configured to provide a resonant response to an optical field at a different spectral band and to couple the resonant response with a waveguide. The waveguide is configured to propagate the different spectral bands in a direction of a user's eye.

See-through display for an augmented reality system

Apparatus for generating THz (terahertz) radiation, the apparatus comprising: a substrate; a planar array of asymmetric point antennas formed on the substrate and excitable by a pump pulse of radiation to radiate THz radiation the point antennas having characteristic dimensions substantially smaller than wavelengths of the radiated THz; wherein the array comprises point antennas aligned in different directions.

Tailored terahertz radiation

An array of optical resonators includes at least a first type of optical resonators each having a resonant response to an optical field at a first wavelength, and a second type of optical resonators each having a resonant response to an optical field at a second wavelength, being different from the first wavelength. The resonant responses can be selected to reduce chromatic aberrations, or to shape a profile of a light beam, or to selectively switch a near field beam.
