  • Patent number: 10345631
    Abstract: A spatial light modulator includes an array of Faraday domains with each Faraday domain being selectively magnetizable to serve as an individual magnetic domain for selectively changing a polarization state of electromagnetic waves, having wavelengths that are no greater than a maximum wavelength, passing through each Faraday domain with each Faraday domain being characterized by physical dimensions and each Faraday domain is selectively magnetizable so long as the physical dimensions do not exceed a given maximum set of dimensions that correspond to the maximum wavelength. An addressing arrangement addresses the array of Faraday domains to selectively switch a magnetization state of a group of adjacent ones of the Faraday domains such that the Faraday domains that make up the group of Faraday domains cooperate to selectively change the polarization state of at least one electromagnetic wave passing therethrough having a wavelength that is longer than the maximum wavelength.

  • Patent number: 10330947
    Abstract: Mirrors, lenses, devices, apparatus, systems and methods for correcting temporal dispersion of laser pulses or other pulses of electromagnetic radiation in diffractive telescopes used in applications, such as but not limited to optical telescopes, transmitters, receivers, and transceivers for laser communication and imaging. Diffractive lenses and mirrors allow for producing large area telescopes and reducing or eliminating temporal dispersion of laser pulses and other pulses of electromagnetic radiation recorded by such telescopes. This can be achieved by utilizing high efficiency thin film diffractive optical films, particularly, diffractive waveplates, and having a secondary diffractive mirror of a shape selected to assure that the propagation time from the flat primary collecting lens or mirror is independent of the position on the flat primary collecting lens or mirror at which the radiation impinges.
