Beam steering and lateral hole burning in mid-infrared quantum- cascade lasers

We investigated the beam‐steering phenomenon of quantum‐cascade lasers emitting at ∼7.8 µm wavelength, operated in pulsed mode at heat sink temperatures around room‐temperature. The lasers have a dimension of 12 µm × 1500 µm. The observed beam‐steering phenomenon has been explained by considering sp...
