Abstract

In this work, single-mode distributed feedback interband cascade lasers with tapered ridges are presented. The lasers consists of a 500 μm long and 5.7 μm wide ridge wave guide section followed by a 1400 μm long tapered section with an output facet width of 35 μm. The device is operational in continuous wave mode and well above room temperature. At 25°C, the threshold current and threshold current density were 81 mA and 324 A/cm², respectively. We demonstrate a tuning range of over 14 nm with side mode suppression ratios larger than 25 dB. The device showed temperature and injection power tuning coefficients of 0,35 nm/K and 4.09 nm/W, respectively. Output powers of 18 mW single mode and 35 mW multimode were achieved.
