We have studied the effects of compressive and tensile strain of single quantum well lasers on differential gain, transparency carriers density and threshold current density. Aluminum composition is adjusted at 0.07 and 0.09 for compressive and tensile strain respectively. In both compressive and tensile strain quantum well, the minimum threshold current density was achieved at 1.5% strain as 110 Acm-2 and 125 Acm-2 respectively, with a cavity length of 400 µm.
