In-fiber single-polarization diffraction grating based on radiant tilted fiber grating [PDF]
Optics Letters, 2019 In this Letter, we propose an in-fiber single-polarization diffraction grating based on a radiant tilted fiber grating (TFG), in which the s-polarization light could be diffracted from the fiber core to free space with the wavelength-dependent diffraction angle.

Interrogation unit for fiber Bragg grating sensors that uses a slanted fiber grating [PDF]
Optics Letters, 2004 A novel interrogation technique for fiber Bragg gratings is presented. It is based on measuring the characteristics of the outgoing near-field radiation from a tilted fiber grating. This scheme was experimentally checked and was found to offer a wide wavelength interrogation range as well as a good linearity, stability, and wavelength resolution.
