Abstract
The impurity-free interdiffusion technique has been utilized to modify the operating wavelength of high-speed In0.35Ga0.65As-GaAs multiple q uantum well lasers, Modulation bandwidths of up to 26 GHz (I-bfas = 50 mA) and modulation current efficiency factors of 5 GHz/mA(1/2) are de monstrated for 3 x 100 mu m(2) ridge waveguide lasers following wavele ngth shifts of 32 nm (34 meV). These results demonstrate the feasibili ty of fabricating monolithic multiple wavelength laser arrays in which each element is capable of low-bias-current direct modulation at band widths exceeding 20 GHz.
