Multilayer optical memory with two-photon mechanism for recording
Engineering Education # 10, October 2012
DOI: 10.7463/1012.0479554
The authors present the results of their study of multilayer optical memory with a two-photon mechanism for recording and collinear heterodyne readout. The choice of materials for multilayer recording with a nonlinear two-photon absorption mechanism is justified. The authors give a description of the experimental setup for multilayer recording in the form of microholograms with relative phase modulation. They present the main characteristics of an experimentally validated installation. The authors consider the main sources of additive noise and their impact on the speed of reading and recording density. They empirically obtained a preliminary assessment of the impact on reliability of inter-symbol interference registration information.
