摘要/描述

We investigate near-infrared photorefractivity and the dynamics of refractive index grating buildup and readout processes in reduced LiNbO3: In, Fe. High asymmetry in grating buildup and readout erasure rates is observed. This remarkable property makes the recorded grating quasinonvolatile during readout. The reason for the high asymmetry is explained qualitatively in terms of a multiple-defect-center model.
