Abstract: We report electrically pumped continuous-wave (CW) InAs/GaAs quantum dot lasers directly grown on planar exact silicon (001) with asymmetric waveguide structures. Surface hydrogen-annealing for the GaAs/ Si (001) templates and low-temperature growth for GaInP upper… read more here.

Abstract: Rare-earth-doped fiber lasers are emerging as promising high-power mid-infrared sources for the 2.6-3.0 μm and 3.3-3.8 μm regions based on erbium and holmium ions. The intermediate wavelength range, however, remains vastly underserved, despite prospects for important manufacturing… read more here.
