Abstract
The dependence of laser performance on the active region position in broad-waveguide laser diodes is presented in this paper. Performance of structures with different position of active region is compared in simulation and actual devices. Lasers with active region displaced towards the p-cladding layer outperformed the lasers with active region undisplaced or displaced towards the n-cladding layer both in simulation and experimentally. Maximum output power increased by 25% for devices with active region displaced towards the p-cladding layer.
