Abstract :
Optical intersecting-waveguide switches with curved electrodes are analyzed. It is shown that the electrode-curvature in the form of a logarithmic spiral results in reflected field distributions in good resemblance to the incident one with reduced transverse shifts. Large extinction ratios and low scattering losses with small voltage-length product are, therefore, achievable. It is concluded that electrode curvature in the form of a logarithmic spiral is effective in realization of low insertion loss, high extinction ratios and small size optical switches
