Abstract :

In the process of information technology, as Moore's law becomes more and more close to the limit, it has become inevitable and the consensus to combine microelectronics and optoelectronics to develop silicon-based large-scale optoelectronic integration technology. As the most important part of silicon photonic devices, silicon-based light source still attracted great efforts. In the traditional research, the erbium-doped materials have played an important role in silicon-based light sources. Recent studies demonstrated that the erbium silicate compound had a high net gain attributable to its high erbium concentration that has no insolubility problem. This paper focuses on the theory, designs, simulations, preparation methods, process and device optimizations of the erbium silicate compound optical waveguide amplifier and laser. The erbium silicate compound materials with large optical gains can serve as potential candidates for future silicon-based scale-integrated lightsource applications.
