Abstract:

The method of blazed holographic diffraction gratings fabrication by transformation of an original symmetric grating grooves into asymmetric ones using inclined vacuum deposition of silver and additional chemical etching have been developed. As photoresist material for gratings recording light-sensitive chalcogenide glassy As2Se3 layers were used. The shape of grating grooves was determined with an atomic force microscope. Angular and spectral dependencies of the diffraction efficiency of the gratings were found, and a relation between optical features and the grating surface pattern was analyzed.
