Abstract: A new approach for coherent positive index guided distributed feedback lasers array using laterally coupled gratings is demonstrated. The device fabrication requires no regrowth which makes this concept suitable for a variety of material systems. The lasers are based on an InGaAs/GaAs single quantum well structure emitting around 980 nm with high sidemode suppression ratio of more than 50 dB. [ABSTRACT FROM AUTHOR]
