Abstract :
Summary form only given. We measured the temperature dependence of differential gain of 1.3-/spl mu/m InGaAsP-InP MQW FP and DFB lasers with the same design and two different doping profiles: moderately (2/spl middot/10/sup 17/ cm/sup -3/) and heavily (2/spl middot/10/sup 18/ cm/sup -3/) Zn doped active region. SIMS was applied to control doping levels. Differential gain values was obtained from corresponding RIN measurements. Experiments showed that the change of the active region doping level from 2/spl middot/10/sup 17/ cm/sup -3/ to 2/spl middot/10/sup 18/ cm/sup -3/ leads to a 50% increase of the differential gain for FP lasers at 25/spl deg/C.
