The performance of parallel and Y-junction arrays has been studied experimentally; calculations of modes in Y-junctions, based on a new model are presented. A flat nearfield distribution from a parallel-stripe array has been achieved by spatially chirping the inter stripe distances. A 2/1 Y-junction array in ',ISIS structure has been realised, which lases in a stable in-phase mode up to the mirror damage level. In contrast, we show a 2/3 Y-junction ridge-guide array, with an InGaP active, layer (λ =660 nm.), which does not start in an in-phase mode.
