Ring Cavity Surface-Emitting Quantum-Cascade Lasers with Staircase-like Distributed Feedback Grating
The results on fabrication and experimental study of ring cavity surface-emitting quantum-cascade lasers with staircase-like distributed feedback grating are presented. The grating with a gradient in etching depth of the slits along the ring cavity was formed by direct high-vacuum ion-beam lithography. The lasing was observed close to 7.9 μm at 293 K with maximum output power about 15 mW. Analysis of the near and far field patterns showed that created ring quantum-cascade lasers operated on a high order transverse mode.
