Crosstalk and Ghost Gratings in a Large-Scale Weak Fiber Bragg Grating Array

Journal of Lightwave Technology, 2017
Large-scale distributed fiber Bragg grating (FBG) sensor networks have a wide range of applications. However, serious crosstalk could occur in a near-identical serial FBG sensor network because of multiple reflections. Since crosstalk cannot be observed directly and separately from signal, experimental investigation of crosstalk is challenging. In this

Fiber Bragg grating array calibration

SPIE Proceedings, 2005
A three element, 15.3 cm, fiber Bragg grating array (FBGA) operating at 1550 nm wavelength is fabricated using a single mode photosensitive fiber. The FBGA is initially simulated using in-house developed software based on the Transfer Matrix Method, then fabricated using a double frequency Argon laser and a phase mask technique, and interrogated using ...

Automated Manufacturing of Fiber Bragg Grating Arrays

Optical Fiber Sensors, 2006
By automating the manufacturing of fiber Bragg gratings, FBG arrays with much larger count of sensing points, stronger mechanical strength, tighter optical parameters tolerances and enhanced reliability are produced in a cost effective manner.

Design and fabrication of fiber Bragg grating arrays

SPIE Proceedings, 1999
In this work, the photolithographic method with the improvement of the stretch-and-write technique is applied for the design and the fabrication of fiber-Bragg gratings distributed on different lengths of fiber and with different operating wavelengths.

A microphone array using fiber Bragg gratings

2002 15th Optical Fiber Sensors Conference Technical Digest. OFS 2002(Cat. No.02EX533), 2003
We proposed an optical microphone array using fiber Bragg gratings (FBGs). Deformation of the diaphragm was transformed to the modulation in the center wavelength of the FBG. We demonstrated, the WDM operation of a four-element array microphone as well as the performances of the element microphone such as frequency response, linearity and sensitivity ...

Fiber Bragg grating for phased-array systems

IEEE Antennas and Propagation Society International Symposium 1997. Digest, 2002
Fiber Bragg grating based fiber optic devices are discussed for phased-array system applications. These devices include fiber grating time-delay element, several fiber grating related laser sources and wavelength division multiplexer and demultiplexer. Detailed structures and performance of the fiber grating-based fiber optic devices are also presented.
