            Abstract : 
A phase-matched TE¿TM mode convertor, where the requirement for a birefringence tuning voltage is removed, is demonstrated in Y-cut LiNbO3. The direction of propagation is at 2° to the Z-axis where the sense of this angle is chosen not only to remove the residual waveguide birefringence but to improve the efficiency of the electro-optic interaction.
