  • Publication number: 20170299900
    Abstract: An electro-optic beam controller, material processing apparatus, or optical amplifier, and corresponding methods, can include an actively controlled, waveguide-based, optical spatial mode conversion device. The conversion device can include a coupler, which can be a photonic lantern, configured to combine light beams into a common light beam; a sensor configured to measure at least one characteristic of the common light beam; and a controller configured to modulate optical parameters of the individual, respective light beams to set one or more spatial modes of the common light beam. Actively controlled and modulated devices can be used to maintain a stable, diffraction-limited beam for use in an amplification, communications, imaging, laser radar, switching, or laser material processing system. Embodiments can also be used to maintain a fundamental or other spatial mode in an optical fiber even while scaling to kilowatt power.

  • Patent number: 8849072
    Abstract: An optical device for integrated photonic applications includes a substrate, a dielectric waveguide and a surface plasmon waveguide. The dielectric waveguide includes a dielectric waveguide core disposed relative to a dielectric waveguide cladding and a common cladding. The surface plasmon waveguide includes a surface plasmon waveguide core disposed relative to the common cladding and a surface plasmon waveguide cladding. The common cladding couples the dielectric waveguide and the surface plasmon waveguide.
