We propose a novel thin-film lithium niobate modulators on silicon substrate using thick traveling-wave electrodes. The 3 dB bandwidth can be enhanced to >120 GHz,and half-wave voltage 2 V.

To apply this equation, flat and smooth electrodes are assumed for a capacitor. This essential assumption is often violated for thin-film capacitors because the formation of nanoscale roughness at the ...

Abstract: We present a photoconductive terahertz emitter that incorporates three-dimensional plasmonic contact electrodes to offer record high optical-to-terahertz power conversion efficiencies. By ...
