Project ANCD 19.80013.50.07.05A/BL Technology method of fabrication of holographic diffractive optical elements in thin-film structures of metal-chalcogenide glass semiconductor

Type :International bilateral project, funded by the National Agency for Research and Development of the Republic of Moldova and the State Committee for Science and Technology of the Republic of Belarus
Head :Andrian Nastas, Ph.D.
Duration :2019 - 2020
Division(s) :Laboratory of Optoelectronics “Andrei Andriesh”

The objective of the project is to develop a new technology for the recording of relief holographic diffraction gratings and holographic elements in planar thin films structures metal-chalcogenide glasses (ChG) (Cr-As2S3, Cr-Ag-As2S3, Cr-As40S30Se30 and Cr-Ag-As40S30Se30), using holographic recording procedure in the corona discharge for improving the industrial production of diffraction optical elements. The objective includes the synthesis of ChG, preparation of metal-ChG thin films (Cr-As2S3, Cr-Ag-As2S3, Cr-As40S30Se30 and Cr-Ag40S30Se30), holographic recording of relief-phase diffraction gratings in the corona discharge field, their development by chemical etching with subsequent metallisation. The selection of these materials from binary and ternary ChG systems is due to the high sensitivity to light in a fairly wide optical spectrum.
