摘要
An electro-optic push-pull modulator requiring reduced high switching voltages through combinations of device structure and operation, causing linear and quadratic electro-optic effects to add. Such combinations of device structure and operation include combinations of crystal axis orientation, waveguide structure, electrode structure, electric field biasing, operating wavelengths, and optical polarizations. By inducing linear and quadratic electro-optic effects to add, significant refractive index changes can be realized with lower switching voltages, V pi . Furthermore, significant reduction in switching voltage for push-pull modulators can also be realized through combinations of device structure and operation effectively inducing solely the quadratic electro-optic effect.
