Abstract :
Highly efficient traveling-wave electro-absorption modulators are fabricated with improved multi-quantum well design. The modulation efficiency is as high as 20 dB/V. 40 GHz optical pulses are generated with simple sinusoidal microwave drive. The shortest pulse generated is 4 ps. The experimental co-direction and counter-direction results presented in this works support the theoretical traveling-wave model of operation.
