Abstract

A specially doped photorefractive (PR) crystal Ce:Fe:LiNbO3, and the effect due to Ce and Fe dopants are reported. We have found that the double-doped crystal exhibits higher PR sensitivity, larger dynamic range, broader spectral bandwidth, and lower scattering noise. It is about 10-times higher in PR sensitivity in the red light region (633nm), as compared with the reported data [1]. We have also discovered anomalous enhancement of PR effects which occur at 57°C, 70°C and 110°C. The anomalies are primarily due to possible structural phase-transitions of the crystal at these temperatures. Several applications of this specially doped PR (Ce:Fe:LiNbO3) crystal (both bulk and fiber) are also provided.
