The tilted fiber Bragg grating is a new kind of sensor that possesses all the advantages of well-established Bragg technology in addition to being able to be able to excited cladding modes resonantly as mentioned in this paper.Abstract:
The tilted fiber Bragg grating is a new kind of sensor that possesses all the
advantages of well-established Bragg grating technology in addition to being able to
excite cladding modes resonantly. This device opens up a multitude of opportunities
for single-point sensing in hard-to-reach spaces.read more

Selective Excitation of Radially and Azimuthally Polarized Optical Fiber Cladding Modes
M. Z. Alam,Jacques Albert +1 more
TL;DR: In this article, the dominant polarization properties of the cladding modes excited by tilted fiber Bragg gratings are investigated, and it is shown that by orienting the input core mode polarization with respect to the tilt plane of the grating modes with near complete radial or azimuthal polarization can be excited at well separated wavelengths, as confirmed by experiments.

TL;DR: It is verified that one of the dual peaks at the shorter wavelength is due to the TM mode coupling whereas the other one at the longer wavelength arises from TE mode coupling when a linearly polarized light launched into the Ex-TFG.
