Abstract: An object of the present invention is to provide a magneto-optical material capable of exhibiting the Faraday effect even though no magnetic field is applied. The magneto-optical material of the present invention has a nanogranular structure in which magnetic nanoparticles are dispersed in a fluoride matrix, and can exhibit Faraday properties without requiring the application of a magnetic field because the magnetic nanoparticles are configured by a magnetic material that has residual magnetization and consists of any of a Fe—Pt alloy, a Co—Pt alloy, a Fe—Co—Ni—Al alloy, a Co ferrite, or a Ba ferrite.

Abstract: To enable several orders of magnitude increases in average power and energy handling capability of Faraday rotators, the technology utilizes high speed gas cooling to efficiently remove thermal loading from the Faraday optic faces while minimizing the thermal wavefront and thermal birefringence by creating a longitudinal thermal gradient. A recirculating gas cooling manifold accelerates the gas over the surface of the slab to create a turbulent flow condition which maximizes the surface cooling rate. The technology further provides a spatially uniform thermal profile on the Faraday slabs.

Abstract: A physical package is provided with: a MOT device; an optical chamber which constitutes an optical lattice formation portion; and a vacuum chamber which surrounds these components and has a substantially cylindrical shape. The MOT device is arranged along the beam axis of an atomic beam and traps an atom cluster. The optical lattice formation portion uses optical lattice light that enters therein to form an optical lattice in a cavity, confines the atom cluster trapped by the MOT device in the optical lattice, and transfers, along the X-axis which is a movement axis perpendicular to the beam axis, the atom cluster to a clock transition space which facilitates clock transition. The central axis of the cylinder of the main body of the vacuum chamber passes through the clock transition space, and is set to be substantially parallel with the beam axis.

Abstract: A broadband light source apparatus, and corresponding method, includes a broadband light source configured to provide broadband source light characterized by a source wavelength spectrum. The apparatus also includes a broadband optical filter including both a polarization changer with a length, as well as an exit polarizer. The broadband optical filter receives the source light and delivers broadband output light characterized by an output wavelength spectrum that is a function of the source wavelength spectrum and the polarization changer length and has an output centroid wavelength. The polarization changer length is configured to minimize a thermal sensitivity of the output centroid wavelength. The filter can be configured in view of a particular source wavelength spectrum to thermally stabilize the centroid wavelength and to maximize relative integrated output power passively with respect to ambient temperature fluctuations.

Abstract: A magneto photonic encoder, in plane, includes a set of periodic structures of magneto photonic crystals for rotating a polarization of a beam of light responsive to a controllable magnetic field as it is transmitted through the periodic structures. The rotated polarization, in cooperation with a non-reciprocal-mode conversion device produces an encoded signal without use of crossed polarizers. Path optics guide the light beam into the periodic structures for polarization rotation and then to direct the modified beam of light into the non-reciprocal-mode conversion device. Depending upon the implementation, the encoded output may serve as display image primitive precursor to produce an image constituent signal.
