【Abstract】 Rare-earth-doped active optical waveguide materials have been attracting more and more attentionsince they have good potential as optical amplifiers at 1.34μm and 1.54μm,the standard telecommunications wavelengths.In this paper,the progress in research on the rare-earth-doped active waveguide materials is reviewed briefly.The paper also discusses the advantages and disadvantages of the host matrixes of photoactive species.A novel research field has been proposed,in which rare-earth chelates as active substances are added to various matrixes to obtain active optical waveguide materials.It is suggested that the active waveguide materials doped with rare-earth chelates are promising materials for optical amplifiers in the future.更多还原
