Synthesis and Characterization of Highly Efficient Organic-Inorganic Nanohybrid Materials for Optical Amplification |
| 초록 |
To achieve the superhigh telecommunication system, the development of integrated plannar waveguide amplifiers is extremely essential. At present, Erbium(III)-doped silica amplifiers are widely used. However, the poor solubility of Erbium cations in silica glasses leads to the relatively low optical amplification (OA) gain. To improve the OA gain, the higher Er cations were needed to introduce, but the OA gain reduced, due to the aggregation of Er cations. To overcome this problem, we have designed and synthesized highly efficient organic-inorganic nanohybrid materials for optical amplification by incoporating Er cations into systematic structural ordering of mesoporous materials via sol-gel processes in two synthetic approaches: 1) We first synthesized various mesoporous materials and then filled the erbium-doped silica into the empty pores via sol-gel process through the external modification of the pore surface of mesoporous materials. 2) We also introduced Er or Yb cations into the framework of ordered mesoporous structures in an insitu method and then filled the erbium-doped silica into the empty pores via sol-gel process through the external modification of the pore surface of mesoporous materials. The latter cations could be utilized to get the energy transfer process between Er and Yb cations. In this presentation, we will discuss synthetic method and characterization of highly efficient organic-inorganic nanohybrid materials for optical amplification. |
