Sub-kHz linewidth Extended-DBR lasers heterogeneously integrated on silicon by D. Huang, M. A. Tran, J. Guo, J. Peters, T. Komljenovic, A. Malik, P. A. Morton, J. E. Bowers. 

We demonstrate single-mode E-DBR lasers with 1kHz linewidth and >37mW output power, and ring-assisted E-DBR lasers with 500Hz linewidth, by heterogeneously integrating III-V gain material with a 15mm long ultra-low loss silicon waveguide-based Bragg reflector.

On-chip Detection from Directly Modulated Quantum Dot Microring Lasers on Si

We present on-chip detection from directly modulated microring quantum-dot (QD) lasers grown on exact (001) Si. Static and dynamic properties of the QD-based microring lasers and microdetectors have been investigated. The ring lasers exhibit high temperature stabilities up to 100± C, low thresholds down to sub milliamp, and a wide 3 dB bandwidth up to 6.5 GHz. The microdetectors show small dark currents down to 0.2 nA and eye openings up to 10 Gbit/s with non-return-to-zero signals.
