A Fibre Bragg Grating Sensor as a Receiver for Acoustic Communications Signals
A Fibre Bragg Grating (FBG) acoustic sensor is used as a receiver for acoustic communications signals. Acoustic transmissions were generated in aluminium and Carbon Fibre Composite (CFC) panels. The FBG receiver was coupled to the bottom surface opposite a piezoelectric transmitter. For the CFC, a second FBG was embedded within the layup for comparison. We show the transfer function, frequency ...
متن کاملPart 11: Fibre Bragg Grating type sensors in composites
Introduction Recent studies have shown that Fibre Bragg Gratings are well suited to studying the mechanical behaviour of composites [1]. A Fibre Bragg Grating is a small segment of optical fibre with a core of germanium doped silica which gives a periodic and permanent perturbation of the refractive index. An FBG acts like a selective wavelength mirror, reflecting a particular wavelength (Fig. ...
متن کاملOptimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...
متن کاملGreater Than 90nm Continuously Wavelength- tunable Fibre Bragg Gratings
We report silica-based fibre Bragg grating filters with wavelength tuningspans well over 90nm using a simple set-and-forget beam bending tuning-package. The key operational parameters of the filters are maintained over the entire tuningwindow.
متن کاملDifferential Group Delay Analysis of Uniform Bragg Gratings Written in Hi-Bi Optical Fibers
Fibre Bragg Gratings (FBG) have become key components in optical communications systems, and, in the same time, lightwave transmissions are more intolerant to the polarization mode dispersion. Consequently, the polarization properties of FBG are of paramount importance. In this frame, we analyze the wavelength dependency of Differential Group Delay in the particular case of a uniform Bragg Grat...
