Long-Period Fiber Gratings and their Sensing Applications

International Conference on Fibre Optics and Photonics, 2012
Long-period gratings (LPGs) in optical fibers for sensing are discussed, especially on strain and temperature sensing. Low-cost fabrication by a low-pressure mercury-lamp exposure was described. LPGs in high-birefringence fiber had high strain sensitivity.

Hermetic sealing of long period fiber gratings

Proceedings of SPIE, 2006
A method of writing long period grating and a model to explain light coupling between fundamental mode and cladding mode are presented. One athermal hermetic sealing approach is proposed to form hermetic sealing long period fiber grating. A long period fiber grating was designed and written for this experiment.

Wavelength tunable long-period fiber grating

Fifth Asia-Pacific Conference on ... and Fourth Optoelectronics and Communications Conference on Communications,, 1999
Wavelength tunable long-period fiber gratings in specially designed optical fibers, which have temperature sensitivity of /spl plusmn/15 nm/100/spl deg/C, have been developed. The temperature sensitivity was three times greater than that in dispersion shifted fiber.
