Abstract :
The mid-infrared spectral band encompasses a variety of important applications, including chemical sensing, free-space optical communication, and IR countermeasures. Currently, however, most of the wavelength range between 3 and 4 μm is not accessible with semiconductor sources operating in continuous mode at room temperature. We believe that the most promising structure for bridging this gap is the interband cascade laser (ICL).
