Abstract :
The threshold current Ith of 1.3 μm AlGaInAs devices increases by ~80% over a 1GPa pressure range contrasting with decreases of 10-15% in 1.3 μm InGaAsP devices. This can be explained with 50% nonradiative recombination in InGaAsP and only ~20% in AlGaInAs devices, resulting in a much improved temperature dependence of Ith
