This paper presents a high bend tolerant multimode optical fiber transmission system that is compatible with standard 50 m graded index multimode fiber, in terms of achievable bandwidth and interconnectivity losses. When the 10 loops of the proposed bend resistive Read More …
The design and fabrication of a miniature fiber Fabry-Perot pressure sensor with a diameter of 125 μm are presented. The essential element in the process is a thin SiO2 diaphragm that is fusion spliced at the hollow end of an Read More …
This paper presents a method for the efficient production of all-fiber semi reflective mirrors suitable for fiber sensors and other all-fiber device applications. The mirrors are obtained by the short duration etching of a standard single mode fiber in hydrofluoric Read More …
This paper presents an optical fiber-field access device suitable for use in different in-line fiber-optics systems and fiber-based photonics components. The proposed device u tilizes a thin silica micro-wire positioned in-between two lead-in single mode fibers. The thin micro-wire acts Read More …
This paper presents a maskless micromachining process that can reform or reshape a section of an optical fiber into a complex 3-D photonic microstructure. This proposed micromachining process is based on the etching rate control achieved by the introduction of Read More …
A combination of focused ion beam milling and chemical etching is proposed for the creation of Fabry-Perot cavities in microwires. Both simple cavities and cantilevers are created on 15 ?m-diameter microwires and characterized in temperature. The cantilever structure shows sensitivity Read More …
A system for accurate balancing and controlled unbalancing of the optical path difference in all-fiber optical interferometers is described. Interferometers with various arm lengths (1-30 m) and with initial optical path differences of as much as 1 cm have been Read More …
This paper presents a fiber-optic vehicle axle detector for roadways. It is based on a fiber-optic Michelson interferometer that is mounted directly into the road surface. The fully dielectric design allows for remote operation of the sensor via a long Read More …
This paper presents a low-cost fiber optic anti-squeeze sensor, suitable for use in high-volume cost driven applications. The sensor, used as a car window anti-squeeze detector, complies with EC 2000/4/EC and U.S. Federal Motor Vehicle Safety Standard No. 118. The Read More …
Fiber-optic sensors provide remote access, are readily embedded within structures, and can operate in harsh environments. Nevertheless, fiber-optic sensing of liquids has been largely restricted to measurements of refractive index and absorption spectroscopy. The temporal dynamics of fluid evaporation have Read More …
