Stable above-threshold linewidth enhancement factor in a 1.52-μ InAs/InP (311B) quantum dot laser
01 January 2008
The alphaH-factor behavior with current is investigated in a 1.52 mum InAs/InP (311B) QD laser. It is shown that due to low gain compression effects, no divergence of the alphaH-factor occurs unlike 1.3 mum InAs/GaAs QD lasers.
