## Description

- description: GeSn alloy has emerged as an attractive active material for Si-based
    mid-infrared (MIR) lasers due to its direct bandgap nature at higher Sn concentrations.
    Here, we report on an optically-pumped GeSn MIR lasers based on planar slab waveguide
    with a top Si ridge structure. The inclusion of 10% Sn transforms the GeSn active
    layer into a direct bandgap material. The Si ridge structure ensures appropriate
    optical confinements with reduced scattering loss from the waveguide sidewall.
    Lasing action was achieved under optical pumping with a low threshold of 60.85
    kW/cm2 and an emission wavelength of 2238 nm at T = 40 K. Lasing action was also
    observed up to T = 90 K with a threshold of 170 kW/cm2.
