Abstract :
Summary form only given. In this report, we have demonstrated strained InGaAs-AlGaAs QW lasers employing the n-type modulation doping for reducing threshold current for the first time. We achieved a threshold current density of 200 A/cm/sup 2/ modulation doped three quantum well lasers. The n type modulation doping is applied to InGaAs-AlGaAs materials and threshold reduction is observed.
