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, Co=1.2±0.6×10-29 cm6 s-1 at 283 K, are a factor of over 102 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 To=70 K is measured in the tunneling injection laser compared to 50 K for conventional quantum well structures, |
