Thermal stability of chemical composition gratings in fluorine-germanium-doped silica fibers
2002 (English)In: Optics Letters, ISSN 0146-9592, E-ISSN 1539-4794, Vol. 27, no 12, 1016-1018 p.Article in journal (Refereed) Published
Abstract [en]

A model based on diffusion of dopants in a periodic structure has been applied to describe thermal decay of chemical composition gratings in fluorine-germanium-doped silica fibers. The good agreement between previously reported values and the diffusion coefficients derived here from experiments and models in the 1000 - 1200 degreesC temperature range indicate that fluorine diffusion is the main mechanism of grating decay. Experimental results also indicate that the presence of phosphorous significantly increases the decay rate of chemical composition gratings.
