The threshold characteristics of strain compensated multi quantum well lasers are analyzed theoretically. Taking the InGaAs(P) system as an example, the strain compensated and common strain multi quantum well lasers have been studied. The results show that we can obtain larger optical gain and lower threshold current by the use of a strain compensated structure. The variation of valence band structure plays an important role in improving the characteristics of the strain compensated...
