Abstract :
We demonstrated a switching operation with high extinction ratio in cross state of a fabricated optical switch using Si-waveguide with a ferro-electric liquid crystal cladding. The refractive index matching between ferro-electric liquid crystal and SiO2-Ta2O5 glass was successfully obtained in Si waveguide Mach-Zehnder interferometer.
