Silicon photonic devices can be built using commercial CMOS chip fabrication facilities, or 'fabs'. However, nearly all research groups continue to design, build and test chips internally ...

The devices show lasing at ~10 20 nm with threshold currents as low as 5 mA, slope efficiencies up to 0.5 W/A, and optical powers reaching 1.75 mW, showcasing a scalable pathway for high ...
