Abstract :
A report is presented on long wavelength room-temperature operation of InAs-based interband cascade lasers (ICLs) at 6.06 μm. The broad area and ridge waveguide devices operate in pulsed mode up to 25 and 40 μC, respectively, and therewith extend the available room-temperature operation range of ICLs to longer wavelengths.
