Power and brightness scaling in coherently coupled PCSEL arrays
We report a novel design of coherent photonic crystal surface-emitting laser (PCSEL) array by passively coupling compact photonic crystal cavities in the lateral directions. Experimental characterization results show high beam quality and coherency from our fabricated laser array on InGaAs/GaAs multiple quantum well (MQW) platform.
