Abstract :
In this paper, we analyse the evolution with wavelength of differential group delay (DGD) and polarisation dependent loss (PDL) caused by photo-induced birefringence in uniform FBG. Analytical expression of DGD is reported. We also monitor the impact of grating parameters (physical length, index modulation and apodisation profile) on the wavelength dependency of DGD and PDL. Experimental results complete the study.
