1.3 - Fibre-Bragg-Gratings in Highly Birefringent Optical Fibres for Advanced FBG Sensing Applications

A. W. Koch, F. Jülich & J. Roths
With spreading of the Fibre-Bragg-Grating (FBG) based sensor technology, there is also a growing demand on high accurate sensors. Standard FBG Sensors are typically inscribed into single mode optical fibres, which have some disadvantages compared to other types of optical fibres. It is known that polarisation effects play an important role when using single mode fibres. Therefore Standard FBG Sensors show a dependence of their Bragg wavelengths λB on the state of polarization of the...
