Abstract

An experimental demonstration of a Moire RBG recorded in PTR glass is described. Two shifted RBGs, having respectively central wavelengths at 1547.2 and 1547.4 nm, were holographically recorded in the same plate of PTR glass using expended beams from a He-Cd laser. Then, the sample was developed for 1 hour at 515 degC. After heat-treatment the sample was cut and polished to thickness equal to 6 mm and finally AR coated.
