Abstract
The present invention relates to integrated optic modulator devices and methods for their fabrication. Lithium niobate substrates have waveguides fabricated in them for propagating light energy, preferably in Mach Zhender architectures. The waveguides are bordered by adjacent electrode metallizations of low resistivity, such as copper and silver, to provide the devices with high gain bandwidth products to reduce the cost of drive electronics and simplify processing procedures. Gain bandwidth products exceed 4.5×10,.
