Junction Heating of GaAs Injection Lasers During Continuous Operation
by M. H. Pilkuhn, H. S. Rupprecht
The rise of the junction temperature during continuous operation of an injection laser has been measured as a function of current and is discussed for different cases. The dependence of the emitted light power on current is computed from the thermal data and compared with the experiment. The threshold current and the differential quantum efficiency for continuous operation are discussed.
