By focusing on a hybrid cladding approach, we demonstrate substantially improved device performance of ICLs compared to earlier reported ICLs of a similar design in the 3–4 µm wavelength region. Including a Jth for broad-area devices as low as 134 A/cm2 at 300 K and a peak voltage efficiency of 80%. Moreover, we have demonstrated CW operation of a BA device up to 278 K, the highest CW operating temperature among epi-side up mounted broad-area type-II ICLs, implying improved thermal dissipation with the hybrid cladding approach.
