| description | Dark current-voltage measurements undertaken on a
series of InAs based quantum dot laser structures show
significant variations depending on the growth
conditions of the GaAs barrier layer. A systematic
study of their temperature dependence suggests that
the main mechanism determining the reverse leakage
is due to generation–recombination via mid-band traps
assisted by Frenkel-Poole emission of carriers from
these traps. Since the dark current is a relatively
parameter to determine in a device, optimising this is a
quicker means of optimising the growth parameters
than undertaking full laser testing.
