In this paper we discuss the effects of incorporating carbon doping in semiconductor lasers. Data is presented that demonstrates that very high quality carbon doped epilayers for the fabrication of AlGaAs-GaAs and AlGaAs-GaAs-InGaAs quantum well lasers can be grown by solid source molecular beam epitaxy using a resistively heated graphite filament as a p-type dopant source. Also results are presented that indicate that the use of carbon instead of beryllium improves the contact resistance for refractory ohmic contacts.
