Reflection spectra of etched FBGs under the influence of axial contraction and stress-induced index change

We present a new theoretical model for the broadband reflection spectra of etched FBGs which includes the effects of axial contraction and stress-induced index change. The reflection spectra of the etched FBGs with several different taper profiles are simulated based on the proposed model. In our ob...
