Abstract

Monolithic high density arrays of independently addressable semiconductor laser emitters or elements are able to be placed in close center-to-center proximity, e.g., on 3-10 .mu.m centers, without experiencing any undesirable phase locking and with minimal amount of electrical and thermal interaction or crosstalk occurring between the independently addressed lasing elements and their independent operation. Such design features are highly suitable for high speed raster output scanner (ROS) and laser printing applications.
