Abstract

The diffraction characteristics of hump volume Bragg grating in photo-thermo-refractive glass are analyzed with coupled-wave theory. Results show that the diffraction efficiency of hump volume Bragg gratings (HVBGs) is increasing with the product of refractive index modulation and grating thickness. Keeping the refractive index modulation and grating thickness, the interval between the hump peaks enlarges with the grating period increasing. Keeping the grating period and the product of refractive index modulation and grating thickness, the interval between the hump peaks enlarges with the grating thickness decreasing. Moreover, the angular selectivity of HVBGs is getting better with the larger interval.
