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.

Abstract: Spatially located ultrasound beacons are provided in known locations within a distributed communication system. The ultrasound beacons are configured to emit ultrasound pulses that can be received by client devices in ultrasound communication range of the beacons. The client devices are configured to analyze the received ultrasound pulses from the beacons to determine their time-difference of arrival and as a result, their location(s) within the distributed communication system. The client devices comprise inertial navigation systems (INS) that calculate client device location as the client device moves, and when received ultrasound signals are below a predefined threshold.

Abstract: A fused silica glass article having greater resistance to damage induced by exposure to laser radiation such as laser induced wavefront distortion at deep ultraviolet (DUV) wavelengths, and behaviors such as fluence dependent transmission, which are related to intrinsic defects in the glass. The improved resistance to laser damage may be achieved in some embodiments by loading the glass article with molecular hydrogen (H2) at temperatures of about 400° C. or less, or 350° C. or less. The combined OH and deuteroxyl (OD) concentration may be less than 10 ppm by weight. In other embodiments, the improved resistance may be achieved by providing the glass with 10 to 60 ppm deuteroxyl (OD) species by weight. In still other embodiments, improved resistance to such laser damage may be achieved by both loading the glass article with molecular hydrogen at temperatures of about 350° C. or less and providing the glass with less than 10 ppm combined OH and OD, or 10 to 60 ppm OD by weight.

Abstract: A plurality of spatially located ultrasound beacons are provided in known locations within a distributed communications system. Each of the ultrasound beacons is configured to emit ultrasound pulses that can be received by client devices in ultrasound communication range of the ultrasound beacons. The client devices are configured to analyze the received ultrasound pulses from the beacons to determine their time-difference of arrival and as a result, their location in the distributed communications systems. Use of ultrasound pulses can provide greater resolution in location determination of client devices since ultrasound waves experience strong attenuation in building walls, ceilings, and floors, thus avoiding detection of ultrasound waves from other ultrasound beacons not located in proximity to the client devices.

Abstract: A method of making a silica glass having a uniform fictive temperature. The glass article is heated at a target fictive temperature, or heated or cooled at a rate that is less than the rate of change of the fictive temperature, for a time that is sufficient to allow the fictive temperature of the glass to come within 3° C. of the target fictive temperature. The silica glass is then cooled from the target fictive temperature to a temperature below the strain point of the glass at a cooling rate that is greater than the relaxation rate of the glass at the target fictive temperature. The silica glass has a fictive temperature that varies by less than 3° C. after the annealing step. A silica glass made by the method is also described.
