High-Resolution Fibre Bragg Grating (FBG) Pressure Transducer for Low-Pressure Detection

Locally Pressed Fibre Bragg Grating Pressure Sensor

A spectral-hole created by locally pressing a fibre Bragg grating (FBG)s exhibited a wavelength-shift within the FBG bandwidth. A sensitivity of 74.3 pm/(N/mm) was obtained for pressure applied along the slow axis of a high birefringence fibre. ©2006 Optical Society of America OCIS codes: (060.2370) Fiber optics sensors; (060.2420) Fibers, polarization-maintaining

Fibre Bragg Grating Filters for Optical Communications

Several steps in the development of Fibre optic Bragg grating for application in tuneable wavelength devices intended to DWDM are presented.

Piezoelectric-modulated optical fibre Bragg grating high-voltage sensor

A high-voltage sensor was developed by driving optical fibre Bragg gratings, mechanically fixed along the radial direction, with a conventional piezoelectric disc. A wavelength shift modulation is obtained as a result of the converse piezoelectric effect. The measured output signal is linear. The voltage upper limit depends on the type and thickness of the piezoceramic. A sensor built with a di...

Quantum theory of fibre Bragg grating solitons*

Following the pioneering work of Professor Haus, a general quantum theory for bi-directional nonlinear optical pulse propagation problems is developed and applied to study the quantum properties of fibre Bragg grating solitons. Fibre Bragg grating solitons are found to be automatically amplitude squeezed after passing through the grating and the squeezing ratio saturates after a certain grating...
