Micrometric spatial control of rare earth ion emission in LiNbO 3 :A two-dimensional multicolor array

We report on the preparation and optical characterization of a two-dimensional multicolor emission arrangement obtained by embedding high refractive-index Er 3 + doped CaTiO 3 nanoparticles into a Nd 3 + doped LiNbO 3 crystal substrate prepatterned with an array of microvoids. By controlling the spa...

Description
Summary:We report on the preparation and optical characterization of a two-dimensional multicolor emission arrangement obtained by embedding high refractive-index Er 3 + doped CaTiO 3 nanoparticles into a Nd 3 + doped LiNbO 3 crystal substrate prepatterned with an array of microvoids. By controlling the spatial location of the rare earth ions at the micrometer scale, we show the possibility of simultaneous spatial and spectral control of the spontaneous emission in a two-dimensional rare earth optically activated array. The results can be useful for the development of microcomposite rare earth based photonic devices, such as multicolor emission displays or pixelated color structures.
