Yavich Física, Astronomía y Matemáticas Main parameters of InGaAs/InAlAs multiple quantum well amplitude modulators, such as contrast ratio, insertionloss and chirp parameter, were calculated in order to find a quantum well structure which optimizes them.The parameters were estimated from the theoretical absorption curves, which were calculated for different valuesof applied reverse bias and were compared with experimental data. A study of the device parameters as afunction of the Ga content and operation voltage was performed. The study showed that optimum values forthe modulator parameters cannot be obtained simultaneously.
