Abstract

Electrically-pumped photonic-crystal distributed-feedback lasers with interband-cascade active regions operating in single spectral mode at 3.3 μm are demonstrated. At 78 K, a stripe of width 400 μm emits up to 67 mW of cw power into a single spectral mode with side-mode suppression ratio ≈ 27 dB. The full-width at half-maximum of the farfield divergence angle is ≈ 0.5°, which combined with the near-field profile yields an effective M² of 1.7-2.0.
