Summary form only given. In conclusion, we have demonstrated for the first time a travelling wave driven balanced bridge modulator switch on InP with a bandwidth exceeding 15 GHz. This could be further improved substituting the quaternary waveguide layer by multi-quantum-well layers utilizing the quantum confined Stark effect. For a 1-mm-long travelling wave electrode it would have the potential to handle data with 40-100 Gbit/ s.
