Holographic optical elements and devices based on polyfunctional photo-thermo-refractive glass

摘要

A new polyfunctional photo-thermo-refractive (PTR) glass doped with erbium and ytterbium has been developed for the first time. The glass combines itself three opportunities: fabrication of lasers or amplifiers, recording of volume Bragg gratings (VBG) or holographic optical elements (HOE), fabrication of planar waveguides or fiber. The glass can be classified as optical polyfunctional material. The polyfunctional PTR glass exhibits good spectral, luminescent, and lasing characteristics, as well as photorefractive and ion exchangeable properties. Different HOE and devices on the base of the polyfunctional PTR glass have been demonstrated for photonic applications.
