摘要
Edge emitting diode lasers with highly strained InGaAs quantum wells and GaAs waveguide layers emitting at 1150 nm were investigated focusing on the impact of the waveguide design on fie laser performance. Using a thick GaAs waveguide layer broad area devices with low vertical divergence of 20 degrees FWHM and reliable operation at a power level of 80-mW/mu m stripe width were demonstrated.
