Phase-locked laser arrays through global antenna mutual coupling

2016 
Two-dimensional arrays of short-cavity surface-emitting THz quantum cascade lasers are phase-locked to each other via mutual coupling. A directive beam on the order of 10° divergence and a maximum slope efficiency of 450 mW A−1 is achieved.
