Abstract

We present the first realization of substrate-emitting double-ring Interband Cascade Lasers (ICLs) in Continuous-Wave (CW) mode. The devices are realized in the GaSb material system and emit at around 2.77 µm wavelength. Through the implementation of second-order distributed feedback gratings, single-mode and simultaneous vertical emission through the GaSb substrate are realized. By implementing a concentric double-ring arrangement (diameters of approximately 700µm and 900 µm), two-wavelengths emission on the same optical axis can be achieved, which is desirable for spectroscopic applications. For improved thermal management, the devices are mounted epitaxial side down on custom-made AuSn/AlN heatsinks, enabling individual laser operation.
