Pulsed testing of other ICLs optimized according
to some or all of the features of this invention disclosure has shown the potential for achieving comparable
cw operating characteristics over a wide wavelength
range of at least 2.9-4.2 mm. The lifetimes and Auger
coefficients were extracted by correlating the measured
pulsed threshold current densities and slope efficiencies
of broad-area ICLs with calculations of optical gain vs.
carrier density in the active gain region. The internal loss
was estimated using the experimental slope efficiencies.
The extracted Auger coefficient was found to be relatively
independent of the exact split between the internal efficiency
and internal loss.
