Research progress of Er silicate compound light source materials and devices for silicon photonics application

We carried out a series of basic research for a kind of Si based novel luminescent materials,Er-Yb / Y silicate compounds.We study the structure,optical and electrical properties of these high erbium compound materials including Er silicate,Er-Yb silicate and Er-Y silicate.Through the optimization of Er-Yb-Y composition and structure of Er-Yb / Y silicate compound material,2 orders of magnitude enhancement of photoluminescence is obtained.We prepare optical waveguide amplifier based on Er-Yb / Y silicate thin films,and observe more than 5 dB / cm light amplification.We develop a metal-insulator-semiconductor structure of electroluminescent devices,and obtain Er-Yb / Y silicate compounds electroluminescence,and theoretically prove the possibility that this material can be electrically pumped laser.
