  • Abstract
    In this letter, we present a novel lithium niobate (LN) electrooptic modulator. The proposed modulator incorporates a thin layer of LN and a slotted substrate structure that together facilitate velocity and impedance matching. A full-wave analysis of the proposed modulator is undertaken in order to establish the frequency dispersion effects with respect to the devices microwave effective index Nm, characteristic impedance Zc, and half-wave voltage length product VpiL.
