Paper Abstract

Dual-wavelength method is a research focus in nonvolatile holographic storage. However, both theoretical analysis and experimental demonstration that nonlinear enlargement is inevitable during dual-wavelength readout. By analyzing the speciality of nonlinear enlarge factor, a method of choosing the suitable retrieving angle is proposed, which can prove the uniform enlarge factor and a least efficiency of 44% at a thin thickness such as 10 um to that of Bragg match. In this paper, At last, a novel scheme which achieves simultaneous dual-wavelength readout of two polarization multiplexed holograms is proposed and demonstrated by the experiment.
