Abstract :
We have fabricated 1.3 μm strained quantum well lasers on InGaAs ternary substrate. A low threshold current density of <80 A/cm 2/well and high T0 of >100 K were simultaneously realized. Furthermore, it was found that dg/dn of the sample was enhanced by the effect of the deep potential well. By improving the quality of InGaAs substrates, larger dg/dn should be obtainable
