The nonlinear gain factor of 1.26 /spl mu/m GaInNAs-based SQW lasers, that includes a small amount of Sb to improve the crystalline-quality, was investigated for the first time. GaInNAs-based lasers have an extremely large differential gain of 1.06 /spl times/ 10/sup -15/ cm/sup 2/ in spite of the single-QW; however, at the same time, the lasers have an enormously large nonlinear gain factor of 9 /spl times/ 10/sup -17/ cm/sup 3/.
