Narrow-linewidth silicon-based lasersplay an important role in the field of silicon photonics. In this paper, we have proposed a high performance narrow-linewidth silicon-based Er silicate laser, based on strip-loaded DFB waveguide with a hybrid pump and signal co-resonant cavity. The saturated output power can reach over 90 mW at 1535 nm, with a maximum power conversion efficiency of 66%. The pump threshold is about 22 mW, and the laser linewidth is also as narrow as about 755 Hz. The results provide a new way for future scale integrated ultra-narrow-linewidth silicon-based lasers application.
