Er Silicate Nanowire Light Source for Silicon Photonics

In recent years,Er silicates and Yttrium(Y) and Ytterbium(Yb) co-doped Er silicates have attracted intensive investigations due to their efficient luminescence at 1.53μm.Compared with traditional Er-doped materials,the Er concentrations of silicates are about 1 to 2 orders of magnitude higher due to the stoichiometric nature of these Er compounds.However,it turned out that its large Er silicate waveguide transmission loss and high pumping power required inhibited the possibility of achieving high gain with device size scaled down.In order to solve the problems mentioned above,we use single crystal Er-Yb/Y silicate compound nanowires as the waveguide material to reduce the transmission loss due to fewer defects in single crystal nanowire.In addition,the quantum confinement effect existed in single crystal nanowire can improve the emission lifetime of the erbium,so that it will be much easier to achieve the erbium ion population inversion.In this talk,we will introduce our group recent work about Er/Yb/Y silica...In recent years,Er silicates and Yttrium(Y) and Ytterbium(Yb) co-doped Er silicates have attracted intensive investigations due to their efficient luminescence at 1.53μm.Compared with traditional Er-doped materials,the Er concentrations of silicates are about 1 to 2 orders of magnitude higher due to the stoichiometric nature of these Er compounds.However,it turned out that its large Er silicate waveguide transmission loss and high pumping power required inhibited the possibility of achieving high gain with国家外国专家局国外人才信息研究中心、重庆市人民政府会展办公室、重庆市经济与信息化委员会、重庆市科学技术委员会、重庆市人力资源和社会保障局
