Phase-locked arrays of surface-emitting terahertz quantum-cascade lasers
Tsung-Yu Kao, Qing Hu, and John L. Reno
We report the demonstration of phase-locked arrays of surface-emitting distributed-feedback (DFB) terahertz quantum-cascade lasers with single-mode operations. Carefully designed phase sector locks several surface-emitting DFB laser ridges in-phase, creating tighter beam-patterns along the phased-ar ... [Appl. Phys. Lett. 96, 101106 (2010)] published Wed Mar 10, 2010.
