Fully-Integrated CMOS-Compatible Q-Switched Laser at 1.9μm Using Thulium-Doped Al_2O_3

摘要

A fully-integrated Q-switched laser is demonstrated at 1.9μm using thulium-doped aluminum oxide waveguides, with the potential for achieving an on-chip passively mode-locked laser. All components of the laser are fabricated in a CMOS-compatible silicon photonics process.
