Abstract

The farfield characteristics of a InGaAs/GaAs quantum dots laser was investigated. It was found that the farfield picture on the screen in front of the laser was composed of two straight lines due to the side modes of the junction. And the straight lines consisted of three bright spots, which we believe were presumably originated from the feedback of the substrate and the capping layer.
