Corrosion-induced optical fiber microbending is demonstrated within this article as an efficient method for the design of sensors for the detection and localization of corrosion events on monitored metal surfaces. The proposed sensors were demonstrated in a single point and Read More …
A miniature, fully optically controlled, dielectric, opto-thermally actuated tweezer/micro-gripper that is suitable for the manipulation of small objects is presented. The tweezer/micro-gripper is formed at the tip of an optical fiber and utilizes a mid-power laser diode for its actuation. Read More …
This paper proposes an all-optical-fiber sensor for continuous measurements of liquid levels. The proposed sensor utilizes an optically absorbing vanadium doped optical fiber, which is configured as a long-gauge, optically-heated, fiber-optic, Fabry-Perot interferometer that is immersed into the measured liquid. Read More …
This letter presents a fully distributed forward propagating system, suitable for use with microbend sensors. The principle relies on selected mode launch in specially designed multimode fiber where a short pulse is launched into the fundamental mode. In the presence Read More …
This paper investigates possibilities for the practical design of high-performance multimode fibers (MMFs) that can provide bandwidths in excess of 10 GHz …km in an overfilled regime of operation. Analysis of standard MMF in an overfilled launch demonstrates that the Read More …
This paper presents an all-fiber, fully-optically controlled, optical-path length modulator based on highly absorbing optical fiber. The modulator utilizes a high-power 980 nm pump diode and a short section of vanadium-co-doped single mode fiber that is heated through absorption and Read More …
