High performance continuous wave 1.3 μ m quantum dot lasers on silicon

Abstract

We demonstrate record performance 1.3 μm InAs quantum dot lasers grown on silicon by molecular beam epitaxy. Ridge waveguide lasers fabricated from the as-grown material achieve room temperature continuous wave thresholds as low as 16 mA, output powers exceeding 176 mW, and lasing up to 119 C. P-modulation doping of the active region improves T0 to the range of 100-200 K while maintaining low thresholds and high output powers. Device yield is presented showing repeatable performance across different dies and wafers. © 2014 AIP Publishing LLC.
