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… Continue Reading
Room temperature interband cascade lasers near 7.7 µm and dependence on structural quality
Yixuan Shen, Rui Q Yang, John D Steward, Samuel D Hawkins and Aaron J Muhowski Interband cascade lasers (ICLs) are becoming desirable mid-infrared semiconductor laser sources particularly in the 3–6 µm wavelength range due to their low power consumption. In this work, we report the demonstration… Continue Reading
