Avoiding the requirement for pre-existing optical contact during picosecond laser glass-to-glass welding.
Previous reports of ultrafast laser welding of glass-to-glass have indicated that a pre-existing optical contact (or very close to) between the parts to be joined is essential. In this paper, the capability of picosecond laser welding to bridge micron-scale gaps is investigated, and successful welding, without cracking, of two glasses with a pre-existing gap of 3 µm is demonstrated. It is shown...
متن کاملBound-abrasive polishers for optical glass.
Polishing abrasives that have been bound in a solid matrix can offer several potential advantages over loose-abrasive processes with pitch or polyurethane laps for finishing of optics. These advantages include polishing efficiency, temperature stability, cost of consumables, and compatibility with computer numerically controlled generating machines. Unfortunately, little has been published on b...

Rapid generation of large area polished optical surfaces by high-power CO2 laser irradiation is shown. Results focus on glasses with high expansion coefficients (a>1025/°C) conventio...
متن کاملChalcogenide Glass Optical Waveguides for Infrared Biosensing
Due to the remarkable properties of chalcogenide (Chg) glasses, Chg optical waveguides should play a significant role in the development of optical biosensors. This paper describes the fabrication and properties of chalcogenide fibres and planar waveguides. Using optical fibre transparent in the mid-infrared spectral range we have developed a biosensor that can collect information on whole meta...
متن کاملWine - Glass Micromechanical - Disk Reference Oscillator
The quartz crystal used in the reference oscillator in a wireless communication transceiver is among the most difficult to integrate on chip. On-chip devices capable of matching its Q (on the order of 10,000) and temperature stability (<35ppm over 0-70C) are generally unavailable. Recently, an on-chip vibrating clamped-clamped beam (CC-beam) micromechanical resonator based on MEMS technology ha...
