Abstract :
We have measured the Auger recombination rates in an InP-based quantum well tunneling injection laser from large signal modulation experiments. Measured values of the Auger coefficient, C/sub o/=1.2/spl plusmn/0.6/spl times/10/sup -29/ cm/sup 6/ s/sup -1/ at 283 K, are a factor of over 10/sup 2/ smaller than those measured in similar multiple quantum well separate confinement heterostructure lasers. In effect, the tunneling injection mechanism keeps the carriers "cold" even at high injection levels. A maximum value of T/sub o/=70 K is measured in the tunneling injection laser compared to 50 K for conventional quantum well structures,.<>
