Abstract

A novel low-loss electro-optic Ti–LiNbO₃ TE–TM mode converter is demonstrated. The polarization conversion is not wavelength selective. Extremely high conversion efficiency with an extinction ratio of more than 33 dB has been achieved with 7-V drive. The device is made immune from the optical damage and Li₂O outdiffusion problems typically associated with LiNbO₃ devices by the use of a z-propagation waveguide.
