Abstract

A new lithium tantalate electro-optic polarization modulator using a buried channel optical waveguide is proposed. Utilizing a precisely designed buried channel waveguide, complete phase matching between TE and TM modes is obtainable. In addition, using a periodic poling structure, quasi-velocity matching between lightwaves and a modulation microwave is obtainable at modulation frequencies over 10 GHz.
