A laser array includes a plurality of laser emitters arranged in a plurality of rows and a plurality of columns on a substrate that is non-native to the plurality of laser emitters, and a plurality ofdriver transistors on the substrate adjacent one or more of the laser diodes. A subset of the plurality of laser emitters includes a string of laser emitters that are connected such that an anode ofat least one laser emitter of the subset is connected to a cathode of an adjacent laser emitter of the subset. A driver transistor of the plurality of driver transistors is configured to control a current flowing through the string. 一种激光器阵列包括：在衬底上以多个行和多个列布置的多个激光二极管，所述衬底对于所述多个激光发射器是非本征的；以及多个驱动晶体管，与激光二极管中的一个或多个激光二极管相邻地位于所述衬底上。所述多个激光发射器的子集包括一串激光发射器，所述一串激光发射器连接使得所述子集的至少一个激光发射器的阳极连接到所述子集的相邻激光发射器的阴极。所述多个驱动晶体管中的驱动晶体管被配置为控制流过所述串的电流。
