In this paper, we report the characteristics of the continuous wave laser output of the limaϛon-shaped InGaAsP microcavity laser pumped by current injection.
In order to find the directions of emission far-field patterns are measureed by rotating an optical fiber around the microcavity. We observe high directionality of the limaϛon-shaped microcavity laser. For the analysis of lasing properties we also investigate its polarization and spectrum using the Glan-Thompson
polarizer and spectrum analyzer.
