Paper Abstract

The photosensitivity and thermal decay of DCF Bragg grating written in Yb3+-doped and Er3+/Yb3+-co-doped DCF are experimentally investigated, respectively. Variation of amplitude of reflective-index modulation and effective reflective index with the UV exposure time are observed. Depend on the photosensitivity relations of hydrogen-loaded rare-earth-doped DCF, we fabricate diversiform reflectivity of DCF Bragg gratings with phase mask method, and the best reflectivity of the grating is 99.9%. The thermal decay characteristics according to the different anneal thermal, 100°C, 150°C, 200°C and 250°C are got. These results are very significant to estimate the properties of grating, such as thermal, wavelength and anneal time.
