High power, single-mode operation from photonic-lattice semiconductor lasers with controllable lateral resonance
An active-photonic-crystal (APC) laser based on laterally resonant arrays of antiguides is proposed and demonstrated. Approximately 1-µm-wide, high-index APC sites are obtained by preferential e...

We report high-power continuous-wave (cw) operation of ~9.5 µm quantum-cascade lasers to a temperature of 318 K. A high-reflectivity-coated 19-µm-wide and 3-mm-long device exhibits cw output powers as high as 150 mW at 288 K and still 22 mW at 318 K. In cw operation at 298 K, a threshold current density of 1.57 kA/cm2, a slope efficiency of 391 mW/A, and a maximum wall-plug efficiency of 0.71% are obtained. In pulsed operation, a maximum average power of 317 mW is achieved at 49% duty cycle. The emission wavelength in cw mode is shifted from 9.524 µm at 288 K to 9.547 µm at 313 K near 1.05 A drive current with a temperature tuning coefficient of 0.92 nm/K.
