Abstract:
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 the laser performance. Using a thick GaAs waveguide layer broad area devices with
low vertical divergence of 20° FWHM and reliable operation at a power level of 80-mW/µm
stripe width were demonstrated.
Index Terms:
Gallium arsenide, high-power lasers, semiconductor lasers, waveguides.
