ABSTRACT
Silicon photonics have been investigated broadly and become a hot topic in recent years based on the expectation that it will provide an efficient solution for the “electrical interconnection bottleneck” of CMOS devices. Some important components such as high-speed modulator and detector have already been realized, while a silicon based or silicon-compatible light source have not been developed yet. Er silicates (Er2SiO5, Er2Si2O7) have been attracting considerable attentions as materials for new light source and optical amplifier at ~1.5mm in silicon photonics. We fabricated the Er silicates films with good structural and optical properties by sol-gel method and magnetron sputtering. Now, we are devoted into the design and fabrication of the Er silicates optical waveguide and laser for silicon photonics.
