Polarization Holographic Grating Formation and Diffraction Efficiency Measurement in Amorphous Chalcogenide Thin Films
비정질 칼코게나이드 박막에서의 편광 홀로그라피 격자 형성 및 회절효율 측정
Abstract
Amorphous chalcogenide thin films, especially a-(Se, S) based films, exhibit a number of photoinduced phenomena not observed in other types of amorphous thin films. The polarization holographic grating has been formed in amorphous As-Ge-Se-S thin films using two linearly polarized He-Ne laser light. In addition, dffraction efficiency has been measured by the same laser of a relative lower intensity at the same time.
