Abstract
In this work, we propose an innovative monolithically integrated mid-infrared quantum cascade laser optical frequency comb source at 8.6 μm. The device attains a maximum continuous wave output power of 141 mW at 20°C. Improving device high-frequency response by integrating π-shaped electrodes. When the driving current is 450mA, the laser spectrum is obviously broadened from 10 cm-1 to 34 cm-1 under 25 dBm RF injection, and the spectrum presents an optical frequency comb.
