Development of long-period fiber grating coupling devices
Applied Optics, 2008A long-period fiber grating (LPFG) formed in a single-mode fiber is considered as an effective device to tap light from the core of fiber. This light-tapping property of the LPFG allows a new class of wavelength-selective optical couplers to be realized by using the configuration of parallel LPFGs. Over the years a number of four-port and six-port LPFG

Long-period grating Michelson refractometric sensor
Measurement Science and Technology, 2004This paper presents a single-probe Michelson interferometer that uses mode coupling in a long-period grating to establish the two optical paths in a single optical fibre. The interferometer phase shift depends on the refractive index of the material that surrounds the fibre probe, with the phase sensitivity directly proportional to the probe length.

Thermo-induced long-period fibre gratings
11th International Conference on Integrated Optics and Optical Fibre Communications. 23rd European Conference on Optical Communications IOOC-ECOC97, 1997A new technique for long-period fibre grating fabrication using thermally activated diffusion of a core dopant to the cladding region has been proposed. Gratings written in a nitrogen-doped fibre with the help of a CO laser or an electric are have exhibited an excellent resistance to a thermal decay.
