Traveling surface-waves longitudinally couple several metallic microcavities.
A phase-locking scheme for plasmonic lasers is developed in which traveling surface-waves longitudinally couple several metallic microcavities in a surface-emitting laser array. Multi-watt emission is demonstrated for single-mode terahertz lasers in which more photons are radiated from the laser array than those absorbed within the array as optical losses.
