Abstract
For the monolithic integration of laser and modulator an identical active layer structure is proposed. The combination of different multiquantum wells (MQW´s) allows the reduction of the wavelength dependence of the absorption efficiency and the chirp. First experimental results are reported. Structures with two different MQW types and only one MQW type are compared.
