Improving device performance of type-II interband cascade lasers with room temperature emission wavelengths below 3 μm
Yixuan Shen ; Rui Q. Yang, Tetsuya D. Mishima ; Michael B. Santos ; Xiaojun Wang We report the demonstration of hybrid-cladding interband cascade lasers (ICLs) for a room temperature emission wavelength range from 2.68 to 2.9 μm. Their threshold current density and threshold input power density are substantially lower than previously reported values from superlattice-cladding…
