Abstract

A novel formulation and synthesis method to overcome the thickness limitations in samples of photopolymerizable glasses with high refractive index species is presented. The reported method allows the recording of volume holographic diffraction gratings in samples of similar to 500 mu m thickness with a high optical quality and low scattering. Holographic grating recording is performed in a single coherent light exposure step, resulting in volume gratings of high optical quality. A holographic notch filter implemented in a 500 mu m thick photopolymerizable glass with a spectral bandwidth below 0.3 nm and an excellent filter extinction ratio of <-27 dB is also demonstrated.
