Abstract:
The causes for the saturation of both the continuous-wave and the pulsed output
power of broad-area laser diodes driven at very high currents are investigated experimentally
and theoretically. The decrease of the gain due to self-heating under continuous-wave operation
and spectral holeburning under pulsed operation as well as hetero-barrier carrier leakage
and longitudinal spatial holeburning are the dominant mechanisms limiting the maximum
achievable output power.
