Abstract
We report single-mode operation of phase-locked arrays of surface-emitting distributed-feedback terahertz quantum-cascade lasers. Carefully-designed phase-sector locks lasers in-phase, creating tighter beam-patterns along the phased-array direction (FWHM ≈ 10°). This method allows beam-steering applications at terahertz frequencies.
