Abstract :
Summary form only given. It was shown theoretically and experimentally that an increase of p-doping concentration in the vicinity of a separate confinement heterostructure (SCH) of 1.3-/spl mu/m multiple quantum well (MQW) InGaAsP-InP lasers leads to improvement of the device temperature performance. Tne present work shows that alignment of p-doping profile within the SCH layer allows us to achieve even lower threshold current and to minimize temperature sensitivity of external efficiency.
