Honorable mention for the Corning Student Paper Competition

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.
