Abstract :
Measurements of threshold-current density and incremental efficiency on homostructure and heterostructure GaAs lasers show an increasingly superlinear dependence of gain 
on current density 
with increasing temperature. The index 
in the relation 
satisfies the relation ![n = [1 + (kT/E_{t})^{2}]^{1/2}](/images/tex/1746.gif)
where Et is a measure of the band-tail depth.
on current density with increasing temperature. The index in the relation satisfies the relation where EKeywords :
