ABSTRACT
We report the analysis of the expected effect of polymeric coating on the lateral pressure tuning of fiber Bragg gratings (FBGs). The dependence of the coating thickness and the stiffness of the polymer on the peak wavelength shift sensitivity and birefringence were evaluated using finite element analysis. A suitable polymeric coating with an optimum value of thickness could reduce the birefringence to an insignificant near-zero value and the peak shift sensitivity could be enhanced to almost ten times as high as that of bare FBGs.

For the first time, the exact solution is obtained without using the small birefringence approximation. The...
