Fiber-Bragg-grating-assisted surface plasmon-polariton sensor
Optics Letters, 2006A theoretical scheme for a new surface plasmon-polariton (SPP) fiber sensor with a fiber Bragg grating imprinted into the fiber core for SPP excitation is presented for the first time to our knowledge. In our scheme the energy in the fiber core mode can be transferred to a SPP with high efficiency by means of a properly designed short-period fiber ...

Multiplexed Bragg grating fiber sensors
Proceedings of LEOS'94, 2002By combining wavelength and time division multiplexing the number of sensors which could potentially be addressed increases to the tens to possibly one hundred devices, depending on the strain resolution and measurement bandwidths required. Recently developed fiber draw-tower fabrication techniques should allow the production of such fibre Bragg ...

Fiber Bragg grating laser sensor
Optical Engineering, 1993An erbium-doped fiber laser utilizing a broadband mirror as the end reflector and an intracore Bragg grating as the output coupler is designed and developed. This arrangement is used as a laser sensor to improve interrogation efficiency of intracore Bragg gratings over broadband sensor interrogation methods.

Fiber Bragg Grating differential pressure sensor
2016 IEEE Conference on Recent Advances in Lightwave Technology (CRALT), 2016The present study proposes a novel real time dynamic pressure sensing device employing Fiber Bragg Grating (FBG) sensor. A hermetically sealed chamber with one surface comprising of a glass epoxy diaphragm is utilized for the differential pressure sensing. The pressure outside the chamber is maintained at atmospheric pressure.
