Abstract
Plasmonic structures in lithium niobate are discussed, particularly long-range (low-loss) straight and curved metal stripe waveguides and electro-optic sections. Long-range waveguides are constructed as a thin narrow metal stripe embedded in a homogeneous optically infinite lithium niobate background. Structures are fabricated using trenching, direct wafer bonding and polishing, resulting in metal stripes and features bounded by lithium niobate lower and upper claddings. Theory and fabrication are discussed, and preliminary experimental results are presented.
