used in optical communication and amplifier requirements more and more and more demanding． In optical
communication systems，due to the structure of the rare earth-doped fiber amplifier makes it impossible to be
integrated，people began to consider the development of planar erbium doped waveguide amplifier ( EDWA) ．It
is use of optical waveguides doped rare earth erbium ions to achieve stimulated emission pumping light under．
Of Y³⁺，Yb³⁺，and of Er³⁺ co-doped Al₂O₃ powders，an attempt to increase of Er³⁺ in the matrix dispersion and
uniformity．Reduce the photon quenching centers in the material of the erbium －doped ions concentration， to
study the modulation of different concentrations of Yb³⁺ co-doped material microstructure． And luminescent
properties of Al₂O₃ were investigated， in order to obtain excellent performance of the alumina
luminous materials．
