Abstract
We have investigated multiple width quantum well (MWQW) InGaAs/lnAIGaAs material as a means of broadening the gain spectrum when compared with wafer structure with conventional identical width quantum well (IWQW). MWQW semiconductor laser material consists of quantum wells of different widths in the same active region, emitting light at different wavelengths
