Local doping by Fe in-diffusion in lithium niobate is a powerful technique to create regions of high photorefractive sensitivity useful to fabricate holographic optical elements such as filters, demultiplexers, Bragg mirrors and so on. In this paper the fabrication and characterization of such regions are reviewed, giving practical advices about how to proceed to realize such areas with the required characteristics.

Abstract
Local doping by Fe in-diffusion in lithium niobate is a powerful technique to create regions of high photorefractive sensitivity useful to fabricate holographic optical elements such as filters, demultiplexers, Bragg mirrors and so on. In this paper the fabrication and characterization of such regions are reviewed, giving practical advices about how to proceed to realize such areas with the required characteristics.
