Abstract :
This paper is the first report on dynamic control of birefringence in silicon-on-insulator (SOI) waveguides by electronically tuning the stress in the waveguide. The dynamic stress is induced by a thin-film piezoelectric transducer integrated on top of the waveguide. Integrated piezoelectric transducers are used to electrically vary the dispersion in a silicon optical waveguide.
