摘要：

We report continuous-wave (cw) distributed-feedback interband cascade lasers operating in a single spectral mode (lambda=3.7-3.8 mu m) at temperatures between 20 and 80 degrees C. The first-order gratings were realized by patterning high-index germanium layers on top of narrow ridges with relatively thin top claddings. One device generated over 27 mW of cw single-mode output at 40 degrees C, with a side-mode-suppression ratio >30 dB, while at 80 degrees C it still emitted >1 mW. At 20 degrees C, a second device lased in a single spectral mode with <100 mW of drive power. The tuning range was 21.5 nm with temperature and 10 nm with current.
