Abstract
We report a type-II interband cascade laser grown on an on-axis silicon substrate. We demonstrate continuous-wave lasing operation at temperatures up to 50°C at 3.5µm with a threshold current of 45 mA at room temperature and 20 mW/facet output power. We extrapolate a mean time to failure of at least 300,000 h, which we attribute to the design of the active region eliminating the non-radiative recombination process.
