Abstract: Methods of forming Luneburg lenses and Luneburg lenses formed from same are provided. One method includes providing a spherical core formed of a material with a substantially uniform dielectric constant from a center of the spherical core to an outer surface of the spherical core. The method further includes forming a plurality of holes that are substantially uniform in size and symmetrically located about the center of the spherical core. The method further includes forming an at least one outer layer that is substantially spherical by winding a filament formed of a low-loss material around the spherical core.

Abstract: A method of laser bonding glass ceramic to metal foil includes contacting a first surface of a first glass ceramic substrate with a first surface of a first metal foil to create a first contact location between at least a portion of the first surface of the first glass ceramic substrate and the first surface of the first metal foil; and conducting a first welding step by directing a laser beam on at least a portion of the first contact location to bond the first glass ceramic substrate to the first metal foil and form a first bond location and a package. The first glass ceramic substrate has a thickness greater than or equal to 20 μm and less than or equal to 250 μm. The laser beam comprises a pulsed laser comprising a wavelength greater than or equal to 250 nm and less than or equal to 2 μm.

Abstract: The liquid-assisted micromachining methods include methods of processing a substrate made of a transparent dielectric material. A working surface of the substrate is placed in contact with a liquid-assist medium that comprises fluorine. A focused pulsed laser beam is directed through a first substrate surface and through the opposite working surface to form a focus spot in the liquid-assist medium. The focus spot is then moved over a motion path from its initial position in the liquid-assist medium through the substrate body in the general direction from the working surface to the first surface to create a modification of the transparent dielectric material that defines in the body a core portion. The core portion is removed to form the substrate feature, which can be a through or closed fiber hole that supports one or more optical fibers. Optical components formed using the processed substrate are also disclosed.
