ABSTRACT:
An electro-optic infrared modulator is provided that it contains an optically buffered waveguide. The buffer comprises a dielectric layer on the top and bottom surface of the waveguide which provides enhanced optical isolation and enables improved synchronization between the microwave and optical waves traveling in the waveguide.
