Abstract

Waveguides made by metal diffusion in ferroelectric crystals - principally titanium diffused in lithium niobate - have become the basis for a variety of interesting and useful guided-wave devices². The combination of good electrooptic and acoustic-optic effects, low propagation loss³, commercially available substrates and fabrication ease make metal diffused waveguides highly suitable for guided-wave switches, modulators, wavelength filters, mode converters, deflectors, etc.
